The author remixed this model.
My original designs have all been in Tinkercad, but I have taken the opportunity to learn Fusion360 and modeled this. The sideclick half was taken directly from tillig's version, and the body was inspired by Bobbylebob's armor design. I gave the cap two holes and bumps so that it can latch closed. If you need to take it off to change batteries, I have found the easiest way is to rock the cap back and forth while pulling.
I have attached the model in .3mf form. If you open it in prusaslicer and turn on organic supports you should be all set. You don't need supports for the majority of this model, that is why I painted them on for you.
Enjoy!
