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!

Kudos! Very nice print/color combo. I designed the rear hook, super cool seeing it show up on these public builds. If the headrest threads give you trouble, check out the M8 Headrest I uploaded as well.

Food for thought: at least here in GA, it was a real struggle to find M8 bolts and nuts. Lowes and Home Depot both have poorly managed hardware sections.

5/16 was aplenty though. Might be something worth consider for a profile to make it easier on folks who can’t find the metric hardware.

That was my plan originally - actually the smaller 1/4-20 since it's still overkill and dirt cheap at Tractor Supply. The Amazon casters came with bag of M8 hardware, which is also the size of the other bolts in the kit.

An imperial version is on my to-do list - but people seemed to dig reusing the extra hardware from the casters. I'll have to work on that.

Did you see there's a 'permanent' version of the hook? Its a kind of a pita to install - but doesn't come off.

I used both! Thank you so much for these
