I cleared off a shelf by mounting 3 of these racks to display my benchies, so that I can quickly see what spools of filament I have stashed away in various drawers and cabinets. I used Amolen dark wood filament, sanded the visible surfaces thoroughly, and stained them with Varathane red mahogany penetrating stain. If you didn't know better, you'd think it came with my desk.
This model accommodates 6 pairs of benchies, for a total of 12. If you would like a different width, you can use the Customizer on Thingiverse to create a rack between 1 and 12 pairs wide.
I printed with the front of the racks on the print bed, no supports or brim required. I used Magigoo adhesive to prevent warping and to ensure solid adhesion.
I installed the racks using small wood screws, but you could also use 2-sided 3M tape.
This isn't technically a remix, but credit to Nanator for coming up with the concept first.
