3D printed PCB corner block.
Print the base and two of the screw STLs.
Screws are held in place with M3x16 screw, washer and spring ( approx 8 dia x 10mm long)
Takes two 10mm dia x 5mm high Neodumium magnets
If anyone has a dire need for these in aluminium let me know as I can CNC them.

Here's a straight version, for when the PCB is hanging over the edge of the base. Uses the retainer from the corner block .zip above
Here's a longer version of the corner for when the PCB is hanging over the left edge of the bed..
