French Cleat
thingiverse
Needed to hang a large canvas picture frame and like how sturdy and easy french cleat mounts are so I made one up. Print these in sets, mount one to the object, one to the wall, and hang away. I printed mine from white PLA, and they are plenty strong enough for a canvas photo. Perhaps PLA+ or ABS if hanging something heavy. I included a step file, and if you edit it you will notice that the side with the gripper ridges is thicker than the other side. This was to compensate for the 3d printer rounding the edges off making it the same when printed and the two halves locking together nicely. Used 4 walls, 50% infill.
