My spouse said, “Hey, we need labels on the shelves.
I found this one and tweaked it by converting it in FreeCAD to a STEP model, then changing the dimension in OnShape.
STEP model included.
Printed in PLA, 15% infill on a PRUSA Mini+ with “15% fast” settings.
The author remixed this model.
Elongated the clips in the direction of the “calendar” 10mm in each direction for a total 20 20mm.
Elongated the label height by 10mm in the Z and -Z direction for a total of 20mm.
Fits a taller lipped shelf.
No change to the rung clip spacing.
