3D Printer Filament Rack

Filament Rack
Filament Rack

This is the gist of the filament rack I built. Not too expensive, not horribly complicated. Easy access to all spools. Framework for potentially added a full enclosure to protect against dust and humidity. And most importantly — cheap!

It has 24 posts, each with the capacity to hold two 5 lb spools (by length that is. It seems like it should be strong enough but no guarantees haha). I used to just slide a bunch of spools onto some pipe or threaded rod or whatever, but changing them out was a pain since you had to move all of the other spools to get to the one you wanted (which was the center one 99% of the time it seemed).

Bill of materials:

  • (5) 2×4 x 8′ lumber ————– ~$2.50 each
  • (2) 1/4″ x 5′ PEX tubing ——– ~$2.00 each
  • (3) 10′ x 3/4″ Sch 40 PVC pipe – ~$2.50 each
  • (24) 1/4″ x 4.5″ Bolts ————– $0.36 each
  • Bunch of 2.5″ screws ———— ~$3.00
  • Cost ———————————- ~$36

Basic info:

  • There is 1 foot of spacing between each holder.
  • 2×4’s are cut to 4′ long for the horizontal beams, and 3′ long for the vertical beams (vertical beams were originally 4′ long but I had to trim them to make it fit in my available space).
  • Bottom stabilizer feet 2×4’s are 26″
  • PVC is cut to 22″ lengths
  • PEX is cut to 1.75″ lengths (2.5″ lengths if you actually have 10′ of PEX. I didn’t)
  • Oh, and you’ll need some hot glue to glue the PEX onto the 2×4’s.
