This is a wall mount designed specifically for the Flyzone DHC-2 Beaver, but it will likely work for any float plane with a crossbar. Using it is simple -- attach the mount to the wall with a couple of screws (3 mm holes are built into the print) and hook on the float crossbar of the plane!It is designed with a bunch of "lightening holes", but although I think they look pretty nice, I'm not convinced it actually saves much filament or makes the thing any lighter, since the printer has to print walls around every hole where otherwise it would just be infill.
