Crystal Radio Tube - two parts

I built a crystal radio receiver.

I built and printed this model instead of using a cardboard toilet paper tube for my radio coil because the plastic offered more strength. Also, my Thing-O-Matic cannot print tall enough to print the tube as a single model. I printed the tube in two parts and glued the ABS plastic together.

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/0KXg4ibA
