This is a spool holder for IKEA Skadis which fits 3 spool with a size of about 100mm diameter and 44 mm thickness. The spools need to have a inner diameter of at least 13mm. Bigger inner diameters work as well (mine have ~ 17mm).

I creted this based on the great work of @ModellDesignB_338796, who designed the original version for only one spool.

Print with support below the spool holder knobs. I would recommend PETG.
