Magnetic Backplate/rear panel for Voron V0.2 - Mostly blocked for use with bottom mounted Blower fans

Remix of reemo3dp's excellent magnetic backplate system. 

The purpose is to allow bottom mounted blower fans to push air past all of your electronics and out the top.

If using the STL, split it to parts and customise as desired. If using the 3MF file, just edit the the infill on the second part to your desired infill type and density.

Works with the 5015 blower rear panel:
