19" Rack-Compatible 1U mount points for 1 5/8" × 13/16" Strut Channel

Strut channels are widely used in the construction industry. They are inexpensive and readily available from any local builder supply store – at least in the US. You can often find them in mechanical rooms, garages, and similar functional spaces.

19" racks are the common standard across both the computer and music industry for mounting professional electronic equipment. There are plenty of commercial options for various sizes of racks. But if only one or two devices need to be installed, even the smallest rack is too big.

These mount point make it easy to attach equipment directly to struct channels that often already exist in the place. You only need to add 20mm or 22mm M3 screws and M3nS square nuts, both are items that most owners of 3D printers already have in their possession. A small M3 washer wouldn't hurt either, but is not absolutely necessary.

Print with extra perimeters for added strength and select the orientation of the layer lines depending on your expected mounting direction as to minimize strain on the printed part. Most filament types should work fine. The part in the photo was printed with Prusament PETG and a 0.6mm nozzle; it is mounted vertically in the final application.
