And here we have a PCB mount plate. The other side is completely flat. I left the ‘Skeleton’ in there because it provides direct support to the PCB. But it probably isn’t necessary, and if it was gone from (so using the three mounts only as contact points) there might be a chance of slightly better cooling (or just more space for sawdust to go)
So version 2
