circuit board mount for 2020

Use two of these to mount a small printed circuit board. For the [COB LED lighting](https://www.thingiverse.com/thing:1873518) I made for my printer, I needed to mount two small circuit boards. I designed these for one of the boards. I have uploaded the OpenSCAD file, so you can tweak the model to your own needs. Use M3 bolts and nuts to mount the PCB, and use M4 bolts and T-nuts to mount the brackets to the printer.
