Ender 3-v2 Control Board External Mount Plate

I needed a way to secure a couple of Ender 3-v2 control boards, so I drew up this mounting board. It allows for two control boards to be secured side-by-side. I've also included a single-board variant. The printed threads in the standoffs are M3. The “speed holes”  around the board have clearance for M3 fasteners and should allow for flexibility when mounting to a larger assembly.
