Original summary

Simple 3 spool holder for organizing loose wires, fairly small only holds 30m of 18awg wire but it is what i had at the moment and think it will hold for a short period of time.

If you like a little more interesting look to your part you can use the included "modifier stl" and set a custom infill with no bottom or top layers.

This explains it much better than I ever could: https://www.youtube.com/watch?v=6PVeh43Or-g

My modifications

The .3mf file is created by me; it has the modifier already applied to the spool, creating a hexagonal pattern (similar to prusament spools).

Print instructions

Generally: PLA, 0.3mm layer height, 15% (gyroid) infill.

For more interesting settings, check the included 3mf file and the resulting G-Code.
