Parametric BNC dust cap

thingiverse

I required a custom dust cap that wouldn't compromise my measurement tool's security with any space between the connector and front panel. This basic design fulfills that need, accommodating connectors of various lengths and capable of being screwed into place with a mere 1/4 turn maximum effort. With the current settings, the dust cap fits a bit loosely on the connector - exactly how I prefer it, but easily adjustable by modifying the parameters in the SCAD file.
