This uses the DDD Printable Wall Control System (github) to mount a multimeter onto a wall control surface. Includes probe holder and some simple cable management.
I used PLA with 20% gyroid infill and no support required.
For the sidepieces I used the 2x0 Flat (Left and Right) models. If you'd like to secure from vertical movement, use the 3x0 Flat sidepieces and then also print a locking spacer of the same width to mount above or below the mount. Then print threaded pin(s) to secure the spacer. I print the threaded pin at 97% size in X-Y dimensions to thread it more easily.
I have also mounted this on 1" wood pegboard using the sidepieces in this model.
I plan to test this with some other brands and types of multimeters - send me a message if you have other dimensions you'd like to use.
The author remixed this model.
Added a variation for mounting a multimeter.
