A remix of the shelf for the excellent Raz's Desk Organizer design.
I printed the original design, but I could not assemble it as the overhangs did not print properly, and there is no orientation which would avoid problematic overhangs/require no supports (which would be hard to remove).
This remix is assembled using M3 heatset inserts into the supports and M3x8mm screws.
The uploaded stl files align with the original Shelf Jig (for Raz's 137mm shelf) hole spacing. If you resize, then you'd need to adjust the hole spacing accordingly.
