Very easy to print adapter for most cardboard spools. The length between the 2 Flanges is 65mm (i just looked into my spools and found 1 wider one)
Rotates effortlessly. Thread is pretty loose (because it does not have to withstand ANY force), so it should work with any printer no matter how bad your printer tolerances are. You might have to modify your spool holder for it to work, depending on what style you got.
I personally had to Sand down the Spool holder to be able to fit it through the adapter, since the flange on the spool holder is just there to prevent it from sliding out (my hole diameter is like 30 and i left the flange at 31,5 ish so it still registers and cannot slide out while being able to slide it through the adapter)
