UPDATED: v3 now longer thread for more narrow Bambu spool

This is a lock nut to fit Bambulab spools both the 53mm and 55mm versions that I have got. I had 2 spools unlock in the AMS and jammed everything up so needed to keep them together. Someone else said they had designed the same thing but I couldn't find it so thank you to IAN POLLARD for the idea!

I printed these on adaptive layer heights with ABS and they worked great. I designed it using a tighter thread allows more friction when tightened.
Uploaded step files too so people can edit and do what they want with them.
