Zefal Bottle Cap

Thank you @Rolik for posting the Bottle cap design. Unfortunately, initial cap did not fit very well after printing.Maybe my bottle is slightly different or it is the printer. I slightly adapted it and also added an attachment ring.

Print it with a rigid filament. Nylon is a good choice. I used PETG (Colofabb XT) und already broke two ;-)
