This case stores 6-AA's, the main electronics, the geiger-counter tube (as a snap-on component), and various interactive components, such as the power switch (left side) and brightness control (right side).

Case Design

This was one of the first useful projects I designed and printed with my 3D printer. The design was partly restricted, because I had to fit the entire case design within the build plate of the 3D printer I had then.

These models were designed using BRL-CAD, which gave me a scripting interface to create the models along with a graphical output view. With this design:
  • The geiger counter base separates the battery storage from the electronics compartment
  • The geiger counter lid u-pipe holds the geiger counter tube as a snap-in item
  • The geiger counter tube holder has several holes, permitting charged particles to pass through
There's certainly several enhancements I'd make if I were recreating this design or printing this design in bulk, but overall the entire design worked as expected.
