This OpenSCAD model is customizable for the number of holes desired on the rack in small, medium, and large. The STL file has 5 holes, and fits diagonally on an Ender-3 S1 bed.
I set this as a remix because I took the original as heavy inspiration, but wanted a customizable model. This version is from scratch in OpenSCAD with a print of the original as reference.
The OpenSCAD model requires the BOSL2 library.
Prints with no supports necessary.
