Bernzomatic Screw On Cap

thingiverse

I designed this cap to be used with Propane or MAP Bernzomatic bottles. It was meant to be easily screwed on, but the thread on the bottle is 20 per inch, which is pretty fine and I couldn't design it properly. So instead I added four little tabs inside the cap, which with a little force will work their way into the thread of the bottle. It worked well for my bottle and stays very tight. If you feel that you can design the thread and get it to work, please do and share.
