A variable capacitor made with parts I had laying around. Used in a magnetic loop antenna (also made with parts I had laying around).

STL files can be found https://www.thingiverse.com/thing:5263587

The two rectangle blocks on either end are print-in-place bearing blocks. The tolerances are fairly tight to keep them from wiggling - had to do some trial and error to find what worked for my printer.
