Snap Together Balloon Bugatti
by petropixel, published
I liked the original, but I made a few changes before printing mine.
(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.
- 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.
- 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).
It doesn't work, so... Learn from my mistakes?
