Trifecta arm

This is designed with Sketchup as a beefed up replacement part for a Trifecta arm which had snapped in a spectacular crash. No replacement arm was available besides buying a new complete kit. In PLA at 100% fill, it weighs approx. 16g, with the original being 15.5g. The motor mounting holes have to be custom drilled to fit your use. Due to the limitation of the printing grain, the attachment region for the swiveling landing gear is extremely weak. That portion for my prints easily and repeatedly snapped off. Please use at your discretion. The rev. 2 designation was simply my attempt to improve on this without success. However, I utilize heli skids for landing gear, so this did not effect my usage.
