This uses the DDD Printable Wall Control System (github) to mount a Craftsman CMHT26028 Hex Key set onto a wall control surface.
For the sidepieces, I recommend using one size higher than the model so that a locking spacer can be added in the extra space. So, I used 3x0 Flat sidepieces, Left and Right, and the 1x1 Locking Spacer to go on top between them. Then use four 4x10x8mm pins to attach the sidepieces and the mount, and finally a threaded pin to secure the spacer. I print the threaded pin at 95% size in X-Y dimensions to thread it more easily.
The author remixed this model.
