Propane Connection Knob

thingiverse

This is a straightforward knob designed to slide snugly over the brass connector nipple found on propane tanks, effectively rendering tool-less bottle swapping a breeze. To achieve this effortless process, one simply needs to print out the design in ABS, then treat it with acetone and slip it onto the corresponding nut for added sturdiness, before securing everything firmly in place with a robust epoxy coating on top of the brass nut.
