Assembly: You have to cut to length 2x fi 20mm or 2x fi 16mm tubes (I used 1m, but this design can hold even more weight than 14 spools, so If you need, you can easily extend it). Under the Tube holes, you have 2.5 mm holes for the M3 screw to secure bolts if needed.
Use 21mm version with 20mm wooden rod (usually they don't keep their dimensions)
That's it. I used 4 parameters and a 10% infill with a 0.6mm nozzle, but that is overkill. 3 parameters with a 0.4mm nozzle will also work.
Happy 3d-printing ;-)
