Umarex Zelos 15rd Magazine .25cal (Version.2)

Same story as my V1 mag, inspired by the 10rd Notos Mag by William Hemmingsen ( https://www.printables.com/model/887509-notos-10-shot-22-magazine ).

This is the second version of my Zelos mag, I've reversed the direction that the drum rotates since the V1 tried to push itself out of the rifle if cycling the lever slowly. This one is also now 15rd instead of 14rd. 

Materials required: 

M2 Self Tapping Screws, 5 or 6mm

.025" OD Music wire for the spring

Magnets, 5mm x 3mm (+some superglue for permanent installation)

Some sort of o-ring, I just used some random 28x31.mm ones that came in an amazon multi-size kit. 

The spring is made the same way as before, wrapping the music wire around a dowel or something about 18mm in diameter. I use a mini maglite. Bend tabs, stuff it inside the drum, juggle things until it winds correctly without binding etc. 

I print in PETG and don't have to do any cleanup, just glue the magnets in, install the spring and oring and it should be good  to go!
