I made some extentions:
- front an rear lipp to screw in MDF bed
- two parts for better printing
- more t-nut slots
- added t-nuts (M4 Nuts or Hex screws)
- added new PCB holder for smal PCB's (see picture)
it is possible to leave the original PCB holder unmounted, but EURO PCBs are to big to handle with the T-Nut Slots so i mount them too.
