This is a wall mount steel sheet holder for any Prusa like print bed sheets.  Each sheet is staggered to allow easier retrieval of the sheets.  It is designed to be mounted with the V at the bottom.  The minimum length supporting the sides of the sheets is 100 mm.  You will need ample room above the holder to add and remove the sheets.

The included stl is designed for six sheets and held to the wall with two #6 wood screws.

I have included the scad file if you would prefer to modify it to suit your needs.

Printed as shown with brim.

No supports.

.3 layer height (draft mode)

Prusa Mk3S takes around 13 hours to print.  Elegoo Neptune 4 only took 5.5 hours. YMMV

If I print it again, I will probably add some kind of grid / hexes / teardrops to remove some of the weight and (hopefully) shorten the print time.
