18650 hotshoemount container

thingiverse

I designed this to fit a 18650 cell on top of my camera, powering Arduino-driven triggers. I utilize a hotshoe splitter to mount both my Arduino projects and this battery. Assembly is straightforward! Just screw it together as shown in assembly.jpeg, using only a little superglue to permanently secure the foot into the middle piece. Don't forget to screw on the nut before applying superglue; otherwise, you'll have to reprint some parts! I removed the plastic protection from one side of two jumper wires and inserted those ends through the endcap holes. The contact is made by sandwiching the battery cell between the endcaps with the wires touching the battery terminals. Print everything once except for the endcap, which requires printing twice to create one holder.
