Coil shelf kit

I designed this spool holder shelf to be installed vertically under a shelf, this way I keep all my filament spools tidy. I printed the brackets using an ABS filament so as to be very robust and resistant. I used two broom sticks with a diameter of 23 mm so as not to print the rods as well. For you I also designed the brackets with threads so you can print everything without buying external parts. the brackets have two 3mm holes each with a 10mm countersink so as to insert the screws and secure
