SMA connector thumb nut (dust cover)

This is an finger-turnable protective dust cover nut for SubMiniature version A (SMA) connectors used on various pieces of radio and optical equipment. It was remixed from MikkoP's original model to add an extension allowing it to be turned when attached to the recessed SMA 906 connectors of Ocean Optics spectrometers such as the USB2000 or USB4000.

Best printed with the threaded opening facing up at 0.1mm layer height. It has worked for me when printed with a 0.6mm nozzle, but the fit is a bit better when printed with a 0.4mm nozzle.
