I needed someplace to store my not-in-use Snapmaker Artisan build platforms, so I designed this bracket and clip system.

The bracket has mounting holes spaced 11 inches apart to match the M6 threaded holes in the side of my steel workbench, but I've included a STEP file so you can modify the spacing and size of the mounting holes (or anything else) if needed. The bracket itself can be printed with most any rigid or semi-rigid filament; I used Elegoo Rapid PLA+. If you need two brackets side-by-side, I'd recommend using your slicer to create a mirror image for one of them, as I did.

The clip is optional. I included it because the vibration my workbench undergoes while the Artisan is in action causes the platforms to "walk" themselves out of the bracket otherwise. The clip should be printed using a filament with some amount of flex, such as PETG; I actually used PETG for the clip in my make. It attaches to the ear in the side of the bracket using an M3x16mm flat head machine screw. The clips for complementary brackets can be printed without mirroring.
