Printed the original version in 30% PETG, and it snapped near the wheel screws. Re-printed in TPU and there was too much flex. Reprinted in 100% PETG, and lasted much longer, but snapped again in the same place as the first. Admittedly, they both snapped when jumping down curbs :D
This version is a reinforced version of the original, with the hole diameter of the wheel screw reduced to increase thickness, and covered over the front of it, as well as supporting/thicker joints between the main body and arms, and a cross support within the body section. Also stripped the text out of the inside to avoid weak spots. Will need to snip down a cover/cap - will post an amended version of that part if time allows.
