Civil Defense Geiger Counter Prop

This started as a long shot project for a friend of mine in order to get a bit more experience dealing with Arduinos, circuits, soldering, etc and turned into a wonderful time. As such, I have thrown in a number of electronics to simulate a Geiger counter, but what I did is not exactly necessary for any parts of it to function.

On to the printing. The front and back plates were printed on a MK3S and go right to the edges of the plate. There is no room for a skirt, but I experienced only minor lift; your mileage may vary. The main body of the box was designed specifically to print on a Creality CR-30 belt printer and with supports will not fit on a MK3S. If you do want it to fit, you can make it happen by removing the shoulder strap brackets on top. It will most likely turn out cleaner and a better print that way. If anyone reading this has used a CR-30, you know the issues. If you haven't, you can see it in the images.

The gauge face plate, stick, stick cap, knob, and detent are all printable on a Prusa Mini. The stick topper should be installed even if you are not planning on adding a sensor to the stick like I did, as it cleans up the aesthetics of the holes I designed in order to fit said sensor.

Hardware to attach everything:

6* M3x20 screws for the gauge plate

4* M3x8 screws for the front and back plates

10* M3 nuts

You should be able to bump those up to M4s, but the bad print I got on the body limited me to M3s.
