rc aircraft ceiling mount

thingiverse

A ceiling mount for models allows them to be lowered to the ground without using a ladder. It incorporates a ratchet system that makes lowering and raising easy. Test with at least three times the weight planned to mount from it for 24 hours or more to ensure it doesn't come loose. Use complete STL files for the guide on assembly. Attach a stretchy spring to the spring pin and the ratchet hook to prevent slipping. To print (for one bend and one ratchet): Print axle support four times. Print axle once. Print lower body four times. Print upper body twice. Print ratchet and axle once. Print ratchet hook once. Print spring pin once. To set up: Assemble parts and attach a piece of string completely around the ratchet axle, then glue it solidly. Screw the ratchet onto the wall (with a washer) where you want it to be. Screw the bend into the corner of the ceiling and run the string through. Screw a loop screw directly above where you want the model to hang and run the string through. Attach the string securely onto the model when it's on the floor, so it balances. Wind the model up.
