Differences of the remix compared to the original
Self centering rollers for Ultimate Spool Holder. There are versions for 1kg and 2kg spools. The 1kg rollers will benefit from additional traction, so printing from TPU is recommended. The effect is subtle and will gradually center the spool on the roller.
The 2kg roller has enough traction from the weight of the spool itself and will slowly deform if printed from TPU. So I recommend printing the 2kg roller from a rigid material like PLA.
There are also rails that are more printable than the original ones.
All files are pre-oriented for printing.

2024-10-22: Regenerated models
After a bit of thinking and realizing that the 2kg roller model, which was directly modeled based on the original model is effectively wide enough for 2 x 1kg spools. All of the 2kg spools I have are significantly thinner. So the new 2kg model has been made narrower, targeting 100mm wide spools, which matches what I have. The old 2kg spool has been converted into 5kg spools, which seem to have a width of around 150mm.
