EDIT:
best results remove the part that clips through the spool with the feeding eye!

You need to make sure you put the tangs towards the printer or it might snag

This is to take the lock ring off the drive side of some RS7 Middleburn Cranks, so you can change the spider or uno chainrings.

I made up a couple of different lengths of Gopro straight and 90 deg extension arms.

I have included the Solidworks file so if you want a different length you can just add it in the design table in configurations and it should all up date

happy printing
