This is a motor mount i knocked up after snapping a couple of the flimsy standard fiberglass ones. Idea stems from a design Physics_dude posted over on http://thestuffwebuild.com/ suits smaller motors using the motor mounts with 34mm spacing. i've printed in Polycarb, 10mm brim using ABS juice to keep it all stuck down. .75mm walls .6mm top and bottom layers 20% infill. plenty strong enough for 1000kv motors and 10x4.5" props doesn't interfere with landing gear. although it may make your motor/esc cables a tiny bit tighter than you'd like due to the extra length.
