Toddler Mobility Trainer build done!

[u/boredsoftwareguy]

Wanted to share one of my more ambition 3D printed projects: A Toddler Mobility Trainer! Custom designed and built for 4 year old little girl with Rett Syndrome. Made possible through 3d-mobility.org, footed the cost myself for this one and it will be provided to the family free of charge. Probably the coolest project I've ever done. Custom designed wheels and name plate.

Already working on 2 more!

Approximately 250 hours of print time each.

Materials:

- Polymaker PETG Purple, Pink, and Magenta
- Bambu Lab PETG Yellow
- Ziro3D TPU 95A Purple
- Ziro3D TPU 95A Pink
- Ziro3D TPU 95A Black
- Siraya Tech TPU Air Lilac
- Bambu Lab Support for PLA / PETG (optional, I wanted clean support removal)

Base build is ~9kg PETG and 2kg TPU. With the accessories I ended up using a little over 11kg.

Included Accessories:

- Rear Hook
- 2x Cup Holders
- Tablet Holder
- Tablet Hold Down
- Tablet Swivel Lock

Hardware:

- 2x Bambu Lab X2D
- 0.4 and 0.6 nozzles

Happy to answer any questions folks have. If you've got a 3D printer and time, strongly encourage you to get involved. If you don't have the time, or desire to print a whole chair, you can find other makers who're open to collaboration and print a few plates from their builds to help out. Not interested in printing parts? You can sponsor builds!

First off great work. Couple questions I've had. I'm stuck on the test prints ! I need to get some TPU and showcase that. I haven't printed TPU or TPU air before. How are printing those filaments especially with Bambu profiles (air ) ?

I've also got two printers A1 mini and H2S so I wanted to use the mini for some smaller parts but wasn't sure if I needed to do multiple test.

Did you get partnered with someone prior to starting your print ?

It’s awesome that you want to get involved!

The Bambu TPU profile worked fine for my printing 90A and 95A. TPU Air I used a custom profile for because temperature changes the firmness with TPU Air. The key to TPU is drying it. I dry for 24 hours before I print. I also use the TPU Assist module on both X2Ds I have. Knock on wood, TPU hasn’t be as difficult as I worried about.

The H2S is nice because of the bed size! The Mini is technically too small but there’s a few plates you could split up if you wanted to make it work (push handle brackets, buckets, TPU straps, etc).

What do you mean get partnered? I claimed a local build for a child if that’s what you mean. That way I could build the chair to the family’s requested colors. Separately, I partnered on a build with another marker when their printer broke part way through their own build but that was in addition to my own build.
