Needed a tape holder for the garage and work van. Knocked this up. Designed it so no supports needed and so you can see all the tape colours.
Holds tapes up to 78mm diameter. If you need a little bigger or smaller just scale up or down. The holes are 125mm apart so I can mount to my peg board which is 25x25mm holes spacings.
Profiles added are for PLA and PETG at 0.28 and 0.2.
0.28 leaves a tiny bit of stringing on the main overhang but it cleans up with a knife. I printed mine in BL PETG-CF
Enjoy
