Threaded nut for 12V Car power adapter

thingiverse

I grabbed a 12V cigarette power receptacle for my DIY exercise bike, but somehow I lost the nut to keep it secure. So, off to Fusion 360 we go. The threads are isometric with a pitch of 1.5mm, but Fusion only had threads for M28 and M30, and this thing falls somewhere in between. I tweaked the standard library a bit and managed to come up with something that actually worked. It's a bit tight, so maybe expand it by a few percent in both X and Y directions before printing. Otherwise, PLA is cheap, and you can do it again easily enough.
