Do you hate those spools of silicon wire that unwind themselves the millisecond you take them out of the horrible cardboard box they come in? I know they're in the box for a reason, but they're ugly and I want mine to feel at home among the other Gridfinity organisation on my workbench.

This model might be the answer for you! The base is a 1x4, 0.25 unit high tray with holes to guide the wires. The Spool Guard can be printed as many times as needed, and just to annoy everyone (just a little), I added space for SEVEN spools, when they usually come in boxes of SIX! You're welcome!

This will fit the 55mm x 20mm spools. I printed at 0.2mm layer height, on a 0.4mm nozzle.

You can print the spool guards on their side, and make sure you enable support for surfaces touching the build plate. This will create a small support for the ring but not fill in the hole. I set my support overhang to 46 degrees, so the 45 degree reinforcement ring prints without support.

I've uploaded a couple of images showing what this looks like. I separated the black and red, using the 7th spool space ;)
