This is a shelf based on an OBS Chevy (88-98).

I have included 2 sets of .3mf. One set is for X/P/A1 series (256mm beds), the other is for the H series printers.

Assembly only requires some glue. The thin part of the tailgate bracket faces front.

Also pegs are included to put into the keyholes, for putting indents in the wall for nail placement. I just used small nails from picture hanging kits.
