Thermometer adapter screw cap

thingiverse

I've managed to break several of the screw caps that come with thermometer adapters, so I fabricated my own. It's not a long-term solution, but it's inexpensive and should withstand use for at least one or two times. If you do print this in PLA, keep an eye on how hot it gets. There are better materials available, but that was all I had access to at the time.
