This is the button for my single 18650 Squonk Mod.
The Frame for the mod can be found here: Squonk Mod Frame
The Front and Back Panels can either be 3D printed as well: Front and Back Panel for Squonk Mod
Or you can get the .dxf file from my website: www.modern-crafts.net
and cut them out of 3mm (1/8") thick wood or acrylic.
