Maturity: Very good.
A spoolwinder easy an fast to mount on a drill. There is no screw. It fits an 6mm hex bit.
The spool winder is for any spool hub in the range 50-55mm.
I found annoying to search for the proper hex bit each time. Then I decided to print one that stay in place in the spoolwinder. Print the one that fits best in yours (5.7mm to 6.0mm available).
