Printed this one long time ago but never published it. Love the design and what Paulo is doing. Keep doing your own thing and not leaning to much towards Bambulab.
Valeu!

Very cool idea, like it very much. Thanks a lot for sharing STEMFIE for free.
The model is easy to print. But from my point of view needs some optimizations. The holes are getting not round enough so that the axis can run freely. The axis doesn’t have enough freeplay, so that manual rework with sandpaper is required. Otherwise, the car drives only 5 centimeters. Would recommend to modify the parts for the axis. (edited)
do any of the parts require supports to print?
@KayanPatel_2509111 Thank you for asking. None of the STEMFIE parts require any support structures.
I am not sure if we can call this a make. We made a couple of cars, but the suddenly they were rebuilt into a crane driven by a mad flexible Dino! Great project, we are printing like crazy.
I love the idea of making educational toys with a 3D printer. PLA doesn't seem to bee the best material though. Will try PETG.
I made this for my science fair to explain the concept of elasticity and it was really successful. The only drawback is that people aren't extremely impressed due to the distance it moves. I also added something to the back
@VoldyTheMoldy_486842 Thank you for your comment! :) I love the addition you made. ;-)
