Hi, this is a Spool Holder i designed myself cause i didnt like the other ones too much. Easy to print and to itall. You can use the original clamp to fix the part. You need: M8 rod around 100mm long M8 nuts (3x) M8 washe 4 4x 608 bearings (diameter 22 / 8 x 7 mm) Do not screw the wing-screw too tight - just hand warm - its enough.
