My body was moving sideways with the normal version and I didn't want to use screws, so made modified Front clip to use clips.
I printed mine out of hard TPU but other materials should work nicely.
You'll need to drill ~5mm holes on the body, you can use the tower screws as a guide (~1mm to the inside of the chassis though).
The author remixed this model.
Front Clip modified so that it uses clips instead of friction to keep front part of the body in place, preventing both lateral movement and escaping on rollovers.
