I wanted a way to bring Multiboard into my workplace, so I could better organize my workspace. I could not find one that fit my cube at work. We have thick walled 80 mm cube walls. I took a part A, and attached it to a design I already had from another item I designed for my workspace, and it works perfectly. It supports everything I have thrown at it. Print Orientation is set in the file.

.2 layer height 3 wall perimeters 4 top and bottom layers 15% infill (I Use 3D Honeycomb)

Photo's coming soon.
