Glock 17, 19, 43X, 43, 42 Mag Holders

These are my first ever models, so please provide feedback.

Forgive the poor line adhesion that can be seen on the completed item.  I was testing a higher print speed, and it didn't come out great there in the middle.

I wanted to clean up my magazines, so I made a few different variants.  

The initial inspiration for this came from this model, but I did create the models on my own, from the ground up.
