Here is my FPV Drone Stand, It holds my 5-inch, but I have tried to design it to hold different frames, some will fit nicer than others, V3 has a wider plate which should help prevent the rear of the quad from slipping off the side,
Perfect Print. A “PP,” if you will. I slowed it down and jacked up the infill to like 50+% just for a nicer finish and a little more heft. Worked great. Polymaker PolyLite PLA Pro metallic gold. Quad in the last picture is a SpeedyBee Master 5 V2.
