This is the new spool holder I made for my Flsun Q5.
I have two types of spools, large with 53 mm center hole and small with 15 mm center hole, so top part is made for them.
You need to print:
There are two mounting positions for bearing holders, so they are higher or lower, just rotate holder and select how to mount it.
