These spacers allow you to mount a variety of things to Muscle Racks. They serve as a starting point for much more complex items.
Currently, I am using these to mount a Muscle Rack to a wall. Because of this, the through-hole is sized for a #6 drywall screw in the current models.
The Solidworks model is parametric for ease of editing to a variety of use cases.
Because I have been printing these from PLA, I have been printing them with 50% triangular infill, 4 walls, and 6 top and bottom layers. This is likely overkill for most use cases but I haven't had a chance to fine tune these as of yet.
