Key label with cover

Two-part key label because all I could find were ones where the paper would either need to be glued in or easily lost. Top part slides in over the paper, and a protrusion around the hole for keyring latches with the bottom, so it's secure.

The paper labels should be a bit less than 40x22mm, with central window sized 14x33 in the middle.

Make sure to flip the cover piece face-down - in default orientation it stands on the protrusion and mostly floats above the table.

FreeCAD file attached. Not spreadsheet but it's simple enough you shouldn't need it.
