Buddy needed a dio reed block as they dont sell them as a single piece anywhere. so, here it is. already printed and test fit, works a charm.

Post Process: not much, a little bit of finishing may be required depending on your exact application

Printing:
this thing will print well on basically anything. no real overhangs, short bridges, no critical dimensions. its a badly tuned printers dream

Infill: eh, whatever you feel like for your own sanity on print speed.

Supports: nah, no need whatsoever, don't waste the filament
