I have been looking forever for a spool rack for the pegboard in my workshop. Maybe I'm searching wrong or maybe it just doesn't exist… Either way, I found a shelf/rack I liked and remixed it to support a pegboard instead of screwing into a wall.

This is also 100% 3D printed with no extra parts. Sure, you could go out and get conduit or wooden dowel, but why when you can print it yourself (if you use the 3mf, just know that I lost a few plates of the 3D printed dowels because the brim wasn't sufficiently large).

All you need is a support every 10 to 11 inches/peg spaces, multiple Spool Dowel 1 files, two Spool Dowel 2 files (for one end), and four Spool Dowel Caps. Basically, the order is Cap, 1, 1, 1, … , 2, Cap with a support at the beginning, end, and for every 2 dowels screwed together.

NOTE: I tested my P1P's tolerances and ended up only being 0.3mm and couldn't get to 0.2mm tolerance, so the screw threads are 0.3mm smaller than the socket threads. If your tolerances are above 0.3mm, the dowels won't screw together.

To see it in action or check out the assembly, check out this convenient video:

Model was printed exclusively with Printbed filament [Note: In the video, the P1P is actually using up some Kinluot I had purchased and used for a custom order]: Gray and Green (prototypes were printed with scraps of Red, Yellow, and Blue). If you are interested in picking up some Printbed filaments, please feel free to use my affiliate link.

At the end of the video, I talk about a great cause that I'm participating in: IC3D's 3D Printed Toys for Tots. If you have spare time on a printer (or spare printers) and filament, please consider signing up for the 2024 TFT campaign. It's a great cause and I hope you check it out and join the rest of us “elves.” Please consider downloading and even boosting my model if you like it or appreciate the design. Downloads and boosts lead to coins which lead to gift cards I can redeem and use to buy additional printers, parts, and filament to continue producing toys for IC3D's program.
