FitBit Aria Scale – Broken Leg Sensor – 3D Print Fix

Hi guys, my FitBit Aria scale sensor had stopped working.

For a while, after every weigh in, I had to keep tapping on it to select myself as a scale user then lift the scale from the ground slightly, to release the pressure on the scale legs, until the scale would settle on my name, otherwise it would keep skipping between all scale users with similar weight without even touching the scale.
It had gotten worse and worse until it would fail with a battery warning, every time it tried to sync the weight to my account, despite the fact that the batteries were brand new.




I’ve followed this video on how to open apart the FitBit Aria scale, and I started to check out the 4 legs to realise clearly 2 of the 4 white plastic discs the scale sits onto, were broken.

Since Fitbit have no spare parts for sale and the scale is out of warranty, it’s pretty much good to go into the rubbish bin.
The scale wasn’t cheap, so I was determined to design the broken part so I can 3D print it in attempt to fix the scale.

To my surprise, I have found kizinfo had already designed the part and posted it free to use here: FitBit Scale – 3D Design part

I have printed replacements for the 2 broken legs, replaced the originals and voila!

It Worked straight away and the issue went away completely.

kizinfo had mentioned in the product description that after 5 months from installing his and using the scale multiple times a day, they were still going strong. Fingers crossed, mine work just fine for now.

Here is my acknowledgement to his design.

And now, as a small token of appreciation, I’d like to give back to the world a little something and hopefully make someone happy out there.
I’d like to print the broken parts for 20 families at no cost (except postage)
. (Australia only please, since freight overseas will cost a bit of money and if the parcel gets lost I can not offer any refunds since I’m not selling anything and I don’t want to seem untrustworthy just because the post/courier had misplaced the package.)

Please make sure your scale is out of warranty before opening it up and contact FitBit first. If they can’t help, then come back here and post below your request for 1,2,3,4(max) pieces, and make sure you type in a valid email address so I can contact you back in regards to the shipping details and my PayPal account for the shipping fee.

Please play fair and only post one request per family and only the broken parts.

    Vio,
    Finding your blog was a like a glimmer of light in the dark trudge thru the net on fitbit aria failings.
    If you still have a couple of these feet left, any chance I could get a hold of them? You’ll save me tossing these scales and also kick start me getting rid of the additional Christmas kg’s (i know, i know, still holding it in April – who am I kidding…).

      Hey Alasdair,

      Ha ha, don’t worry, just because I print them and my scales work fine, doesn’t make me fit at the moment either. Sure, I still have some I can send you, as mentioned above, materials, printing and cleaning of supports after printing is all covered, all you need to pay is the postage of $2.80 the price of a prepaid envelope via PayPal and include your delivery address as a message during the PayPal transaction.
      Hope you fix your scales as it worked for me a bunch of people here, please provide any feedback back her once you replaced them.

      Cheers,
      Vio

        Vio,

        Packaged arrived last night, and thirty mins later i was sweating over the weight loss programme about to kick off…
        Parts went in no bother at all, although i think the third one which was also split (one of the top ones – which doesn’t have the switch contacts) didn’t need changed, as its not involved in switching the scales off. Either way, all three replaced and more importantly the scales are working.
        Your an absolute legend, and re-affirmed my belief that there are good people still out there in the big bad internet wilderness.

        Very much appreciated

    Hi Vio, are you able to do 4 legs for me? Shipping to Sydney
    Thanks mate

    • Vio Post authorReply

      Hi David,
      sorry for the delay in my reply. I sure can. I still have a few already printed. Same process as for everyone else, as soon as you deposit postage cost of $2.80 via PayPal and message me your address via PayPal message, I’ll post them right away. Usually 1-2 business days max since I already have them printed. Hope they work out for you as they did for quite a number of people here.
      Cheers,
      Vio

    Hi Vio,

    Just checking if you’re still able to help with 3D prints for the Aria scale part (I’m in Vic). I’m after 4 if you are!

    • Vio Post authorReply

      Hi Brad, sure can, I have a few already printed I could post them early next week unless you want to pick them up yourself since you’re in Vic. If you want them posted just do a $2.80 PayPal transfer. This seems to be the cheapest I’ve found and is in a prepaid envelope, no tracking but so far everyone got them just fine. Let me know how you want to proceed.
      Cheers,
      Vio

    • Vio Post authorReply

      Hi Isra, sure can, I have some already printed. If you leave in Australia, please transfer the postage stamp cost of $2.80 to my PayPal and I can post them ASAP. Please add your postal address in a message in PayPal attached to your payment.

  4. Heather Phillips Reply

    Hi Vio, I wanted to thank you so much for the Aria feet you sent me. The scale is working perfectly now and is no longer destined to be an electronic boat anchor! Now I just have to get the numbers on the scale to go a little lower and I will be super content! Stay safe & thank you again. Cheers, Heather

    Hello Vio,

    Just wanted to say that the feet came today and after half an hour of fiddling these scales are brand new. You are a wonder and it is incredible to me that an international company like fitbit doesn’t care enough about their reputation to not offer replacement parts for their junk however a stranger on the internet will just print what you need and send them for the cost of postage.

    Honestly you are one of the best things to happen on the internet to me in a long time.

    Keep up the good work.

  7. Michael Roszbach Reply

    Hello! Vio!

    I have just gone through the same frustrating process as all of these other people, to find that my very expensive scale is being defeated by four plastic parts! Would you be able to send me some replacement feet? Please advise and I think it’s amazing that someone is doing this when obviously Fitbit doesn’t care at all!

    • Vio Post authorReply

      Hi Michael,

      I know the feeling, welcome to the club 🙂 I can sure help. If you live in Australia, please send $2.80 for a prepaid envelope via PayPal to my address and add a message in there with your postage address and I’ll post 4 feet replacements. No charge for material, labour or print time/costs, I’ll cover that part. Once received, please post here a message whether they worked for you.
      No probs.
      Vio

      Hi Michael,

      Your feet have been just been dropped off in the post box at the front of the Post Office near me, since it’s the weekend. Please reply to our thread here once you receive them and try them on.

      Cheers,

  8. Heather Phillips Reply

    Hi Vio, I have just worked out I have the same Fitbit Aria issue after trying multiple other solutions. A quick dismantle immediately showed the broken feet. I would like to just pay for 4 including postage to Sydney, as you are providing more than a community service here. I understand you are very busy and I am very happy to wait if you are able to assist. I will Paypal in advance. Kind regards, Heather

    • Vio Post authorReply

      Hi Heather,
      Sorry for the delay, I was busy with a number of things lately and completely forgot to check my site lately. Yes, that is fine, I have 4 feet ready for you, please send me your address perhaps best in a message within PayPal when you deposit the $2.80 for postage to my PayPal address and I’ll post them out on Monday.
      With pleasure,
      Vio

    Hello VIO,
    I searched a bit, unfortunatelly, the some places only accept 100€ orders and the best I found from Italy, all together would be closer to 35€ :/.
    I did not know that you were from Australia, I visited Adelaide last September 🙂
    I am still trying to find other options but it is being hard :/
    Moreover I dont understand much about materials, but I think Multi Jet Fusion – Nylon PA 12 should be suficient, do you agree?

    Best Regards, Joao

    • Vio Post authorReply

      Hi Joao,

      Hope you visited some other places like Melbourne, Sydney, Brisbane.. Adelaide is the least exciting place in Aus for tourism, but if you have friends or family there, it’t a different story :).
      I found PLA works best for this project. Not too hard not too soft and easiest material to print with and they lasted close to 3 years and still going strong. Your best chance is to look for 3d printing Facebook groups. I’ve found there are a bunch of different groups in quite a few countries and ready to help.
      Good luck !

      Vio

    Hello VIO,
    I would like to ask you a couple of those (better 4x just in case) if you can print.
    Please tell me how much it cost to make them and ship them to Belgium and how can I pay you?

    PS: Thanks for the video with instructions.

    Best Regards, Joao

    • Vio Post authorReply

      I wanted to ask you first if you looked for 3D print services near you in Belgium, as I’m located in Australia and I’m concerned they’ll get lost in transit and will be a shame to have paid for postage and not get them and the shipping cost might be as much as getting them printed over there and you will get them sooner that way too… Here is a link to the site that contains the .stl file required to give to the print service: https://www.thingiverse.com/thing:2988535

        Could really use 4 replacement feet.

        Have you shipped any to the US before?

        • Vio Post authorReply

          Hi Tony, I did ship an order once to the US, but it wasn’t cheap, I think was like $15 or around, but I was worried not to get lost as would be a waste of money. Please try first and find someone local with a 3D printer and give them the .stl file and ask them to print you some replacements. I’m sure you’ll find someone ready to help. I’d suggest starting with Facebook 3D printing groups. See how you go. Good luck.

    Hi all,

    Due to current crazy times with the Covid19 crisis, my printer is super busy printing face shields for front line staff in need, therefore all other fun prints will be postponed. There are no outstanding orders but will be paused till further notice.
    I will post here once my printer is ready for fun.

    Thank you for the video, it helped me realize the bottom two feet are cracked, after reading others comments I’m not going to try gluing either. I have a friend in Australia that I could get to send them to me if I can’t find anyone here to print them in Nova Scotia. Do you have a video on replacing the feet?

    • Vio Post authorReply

      Hi Wayne,
      I don’t have a video on how to replace the legs as I remember being so straight forward to do, was only one watch battery size piece that went on top of the printed legs from what I remember, then place the leg back in its place.
      But I was thinking in making my own video on how to open and replace the legs all in one video.
      Thanks for the suggestion.

  19. Michael S Reply

    Hi Vio, I wish I could find a nice person like you in my neck of the woods… I’ve downloaded the printing file and will try to find someone who can print for me. You seem to have done this a while ago, are your replacement feet still holding up?

    • Vio Post authorReply

      Hi Michael,

      I can 100% confirm that my FitBit scale is still going strong and I only needed to replace 2 feet when I published this article under 2 years ago. No issues with it since. Such a basic fix.
      From what you’re saying means you’re not in Down Under are you? If you are, I’m happy to print them and send them to you anywhere in Australia. Otherwise, I’m sure you’ll find someone somewhere to print them out for you.

      Good luck.

      Hi Geoffrey,

      I sure can, can you please reply with your shipping address so I can check the postage cost? I’ll then get some ready for you and once we work out the shipping, I’ll send them over to you. (high likely will be under $5 but I’ll check with the AusPost the cost of shipping to your address). I hope you’re in Australia as otherwise the shipping cost will be too expensive perhaps and with Christmas holidays here, delays and lost parcels can happen and if lost, I don’t want to seem untrustworthy and accountable for the lost parts, which I’m fine to resend if lost but I can’t do anything about the lost shipping cost..
      I’ll be in touch, as soon as I get your shipping address. (and don’t worry your address will not be posted publicly here for everyone to see)

    My Aria got same problem as well. After numbers of resetting and setup until I found the thread on fitbit community and led me to your Blog. I opened the scale and found two bottom legs are broken. Tried glue them but no help. (The glue could not help the tiny contact point and one of the leg has two broken area that could not be fixed.)

    Do you still have the plastic leg parts available? If yes could I get two bottom legs please?

    Please note, I have no stock, I just print them on request, they take a few hours to print and I work full time, so it will be either a weekend thing or sometimes after work during the week, so please be patient and don’t expect a next day delivery. Thanks in advance. Once my 20 orders have been fulfilled, I will mention in the post.
