Hi there :)
this is a simple motor mount for scratchbuild RC airplanes. Ment for 28mm motors on foamboard or depron planes (5-6mm sheets)
This mount is specifically designed for pusher-planes (such as flying wings FI)
The large fin on it serves to protect the propellor (6" prop)
I've added a second version with a much smaller 'fin'...
don't use supports on this print..
I printed it with the motor-mounting-plate on the bed in PLA.. that worked out well :)
Printing without infill works out pretty well (in PLA)
