Recycled Multi-Spool Rack

Since getting one of my 3D printers set up in my classroom, managing the filament spools has been a pain. I finally got around to making a no cost multi-filament holder by using leftover PVC pipe and hardware from other projects.

1/2" or larger PVC pipe (attachments/fittings/couplings as needed depending on how long you want your rack)

Coat hanger hooks

Screws

Drill, screwdriver, measuring tools

Filament is generally housed in larger storage totes, but when actually in use, it's been a pain to make sure the filament is flowing as smooth as it should and not get twisted---which is what was happening.

Because the only place the printer can safely stay in my classroom is by the windows, I decided that putting up a rack of some sort would be the most ideal option. On each side of the center window I measured and drilled holes into the frame where I wanted to put the rack. I used old coat rack hanger pieces from a wall rack that used to be on the back of my classroom door.

I had a whole bunch of leftover pieces of 1/2" PVC pipes and fittings to go with them, so I attached pieces together to make a long enough bar--about 40" in length.

Once your hardware is up and the bar is put together, start loading your filament. I only keep 1-3 rolls on the rack at a time, so far it's working great.
