Finally I can publish the v2 version, I improved a few things, now the batteries do not jam in the magazine, if you are interested in the project, print the available parts marked as v2.

I made CR123 baterrys magazine. To remove the battery, gently push it down and pull it out. Printed spring is not the best solution, so If you found metal one leave link in the comments section. You can also make this device and produce your own steel springs: https://www.thingiverse.com/thing:5025291

For all parts I use 35% infill, print spring with 100%. You need supports only for bottom plate, follower and tube (Use only the supports at the bottom to print the rail).

!!! I made it for 17x34mm diameter, check your batterrys before printing !!!
