Filament Spool Storage Rack Stud-Mount Rod Holder

This mount spans rods from stud to stud to form a cheap shelf upon which rolls of filament can be stored. Each mount supports two rods; should you not have one rod long enough to span three or more studs, you can use the top holes for one rod and the bottom holes for another rod. I had some fiberglass rods left over from a broken child's toy which I used for this purpose. Countersunk holes for two screws. Inspired by my design for a [wall-mounted RipStik rack](https://www.thingiverse.com/thing:2
