3D Printed mount for the awesome GRBLHal Teensy 4.1 breakout board from Phil Barrett. This mount includes provisions for a Micro USB Male -> USB Type B Female adapter allowing it to be zip tied to prevent vibrations from shaking anything loose. Included all source files as well as a version without the USB support. In my controller box I used a piece of steel sheet metal drilled/tapped to mount my motor drivers and other electronics. Used this piece to isolate the board from the grounded sheet metal.
If you notice the copper tape covering the USB connector in my photos, I snaked the USB adapter through expandable tinned copper braiding, covered other exposed areas in copper tape and soldering both to a ground lead in order to shield it from EMI. I'm unsure if it's absolutely necessary but I'd rather not have to go through the process of troubleshooting an issue that could've been prevented with a little extra shielding.
