Playmo school bus

Playmo school bus = hours of fun for your kid!
It seats 12 kids and a driver (preferably an adult).

I made it using TinkerCAD for my kid's 4yo Bday.
I doesn't show too much on the pics, but it warped a bit. I think my Rep2 is due for some TLC.

How-to :
I used small nails for the wheels.
The seats are printed separately and glued to the body.
I've included 3 versions of the body:
- normal blank one (without seats)
- printer friendly version with supports in the windows (so you can print without supports)
- normal with seats included (without supports)

Things that could be improved :
- I figured out (too late) that not all Playmos have the same size and I have to say the fit is a bit tight... So it would be cool to add a few mills here and there.
- take-off roof?
- adding a door?
- adding a steering wheel?
