Created this to be able to allow IIID Max spools to be compatible with the Creality CFS system. Some of the IIID Max spools use these reels that have 8x holes in the center. Print one of each spool design, v4 and v5, for each slot you are using in the CFS. Printing them in PLA is fine so long as you do not have a CFS with the SpacePi mod. If so, use PETG or ASA that has higher temperature resistance.
