A simple bi-plane that i designed in my spare time. The gear and propeller will spin, as the tolerances are very loose. If you are having trouble with printing, don't worry as I will try to include almost every type of CAD file.

Infill:
15% to 30%
Notes:
The only way to get the wheels and propeller to spin is to print this plane with full supports or exterior supports or use dissolvable filaments for the support material (exterior supports will work should work fine, if you feel it needs to be reinforced use full supports). Some features are thin such as the wing struts so limit the amount of shells to at most 2 shells maximum.
After printing to remove support material by peeling it away.
Only do this next step if you have been printing with full supports.
(Optional)Slowly rotate the propellers and wheels back and fourth until you hear the supports snap. Try your best not to snap the proppeler and axels off. This is very tricky as snapping the support material will sound alot like the individual parts snapping.
