Balloon Powered Jet Car with Sweet Rimzzz

thingiverse

Since I didn't happen to have any toy wheels just laying around, I designed some to be printed. Changes from original: -Added sweet rimzzz -Exhaust port changed to round hole, increased size to 7mm diameter. -Wheel mount holes changed to fit small finishing nails -Added lip to balloon stem Instructions Extra Hardware needed: 4 Small finishing nails (3d 1-1/4") 4 m3 washer or similar tiny size Print car and wheels. Use low infill for MAXIMUM POWER-TO-WEIGHT RATIO! Test fit each wheel on a nail to make sure they spin freely. I had to use a fine round needle file to clean the holes a bit. Put small m3 washer on nail/axle between wheels and car body. This might not be necessary, but I had some washers and thought it was a good idea. Tap nails into guide holes. Put a balloon on and have a blast! I've only printed one of these so far and the nail holes were originally way too small. It was bending the nails trying to hammer them in! I had to drill out the holes a tiny bit for a good fit. I changed the script to make slightly larger holes, so hopefully this will work for other people without the need to drill.
