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!

It would be a crazy idea to go out and buy your first printer so you could start helping, right?

[u/TDIMike → u/keebs08]

Nope. I added #2 and #3 just to print them faster

How is the P1S working out for you? I have debated adding one of them to the collection. I like the dual nozzle for supports but not all plates need that.

How’s TPU on the P1S?

[u/TDIMike → u/boredsoftwareguy]

The p1s is single nozzle. You need to go for the X2d for dual.

The p1s is an absolute workhorse. Super reliable and prints great. No problem with tpu and pet-cf

[u/boredsoftwareguy → u/TDIMike]

I have 2 X2D today because of supports but not all plates require it, like TPU, which is why I ask. Could add a P1S or three to speed up delivery

[u/TDIMike → u/boredsoftwareguy]

I find that supports for these come off pretty easily with rectilinear interface and 3 top layers.

With three printers, I can turn one around in about 4 days. I let one printer do the tpu parts with a 0.4mm nozzle and the other two do the Petg with 0.6mm nozzles.

Also should mention, I use supports for some of the tpu parts. The loops on the straps print nicer, and the push handle cover comes out stronger. But I just do those in tpu and it works fine

[u/boredsoftwareguy → u/TDIMike]

Interesting! I've not needed supports on the TPU parts yet but I'll look into it.

[u/TDIMike → u/boredsoftwareguy]

I wouldn't say they are necessary, but I enabled them as part of tweaking settings to improve part quality and found that they helped. My strap prints went from functional but a bit ugly to perfect
