Rubber Band Powered Car

thingiverse

This is the third series of rubber band-powered vehicles that I've created. There are two photos attached to this message showing the previous version of this design. Until this model is printed, I'm facing some challenges. The main issue I'm experiencing is that when I try to assemble all four wheels, they end up with angled holes or holes that aren't perfectly perpendicular, causing the wheel to shake when it turns. Additionally, the upper part of the body is too high, which causes the nut and bolt holes to shift slightly due to swaying during printing. To build this model, you'll need the following materials: 1. M3 nuts and bolts with a length of 10mm 2. One rubber band 3. Two pieces of paperclip cut to 30mm in length 4. Two loose spokes from a bike (diameter: 1.94mm) cut to 80mm in length 5. Rapid cure adhesive, such as cyanoacrylate 6. Lubricant spray, which I used on my bicycle chain
