A box I remixed for my multimeter. The lightning bolt was just a random .SVG I found and put in bambuslicer.
Will require 6x M3x20mm screws for the hinges and latches.
I super glued the insert in so it stays in place. I printed mine out of TPU and set the top and bottom layers to 0 so it just prints an infill grid like a mesh.
The author remixed this model.
Resized to fit and added a custom insert for leads and whatnot.
