Brick Wall

thingiverse

These walls can accommodate three-millimeter diameter magnets inserted up to two millimeters deep, and they are easily found on Amazon. Using these two files, you should be able to create rectangular walls of nearly any size. The design appears suitable for a thirty-millimeter scale miniature game, but it could work just as well for twenty-five to thirty-two millimeter models. I printed my own using an AnyCubic Photon with a layer height of 0.02 and no supports on the build plate. It took nine hours to print this model using Anycubic's green resin.
