I've found it was a bit too much resistance than I wanted with original spool holder and it is too long for filaments I use (Sunlu/Jayo).
Also, I was not able to put small Sunlu reels (250g) without unscrewing the original spool holder first as the edge's diameter is too big.
So I've made a shorter version with sleeve for spools with width up to 64mm.
The original Neptune 4 spool holder is also on the photo for comparison (on the right).
