PCB tray / holder

This is a simple PCB tray for multiple PCBs. It is especially handy for a small volume production or if you what to clean up your space. 357,5 mm x 100 mm or 220 mm x 100 mm It supports PCB up to 2,5 mm in thickness.

I would recommend making an adjustment layer in the slicer and printing the support "beam" in the middle solid for more rigidity.
