Snap Together Balloon Bugatti by petropixel Feb 5, 2013


I liked the original, but I made a few changes before printing mine. -Solid body -Flat bottom -Pin-based axles (These changes were to reduce overhangs, allow for support-free printing) -Scaled down 50%, but kept balloon inlet/outlet closer to original size -Optional spare tire

When I did finally print it, I ran into two problems.

  1. It doesn't roll. Whittling down the axles and opening up the hubs with a drill bit got me wheels that freewheel very nicely in the air, but when I put the car down and push it along they just gain a bunch of camber and slide along, maybe 1 or 2 wheels spinning at a time.
  2. We haven't had a kid's birthday here in quite a while, so the balloons we have pop easily and don't provide much thrust below their bursting point. This is probably easier to fix (just buy new balloons).
