Nikon EN-EL15 battery belt

Wear your batteries on your belt! I thought of those photographers who take thousands of photos and quickly drain their camera's battery. For now I have developed the battery holder for the Nikon EN-EL15 (for Nikon Z7 II, Z6 II, Z5, D850, D810, D810A, D780, D750, D610, D500, D7500), but if the object can please I will develop other models. Suggestions for design modifications and corrections are welcome.

I improved the modular attachment part with more battery holders and enlarged the belt attachment slot. In addition, I created a spring hook alternative that can also fit on the thin shoulder straps of a backpack.
