A pair of screw-in plugs to cover up the BB threads while painting/spraying a bicycle frame. Made for standard BSC 1.37" x 24 tpi threads. RHS plug has a left thread, LHS plug has a right thread.
Print settings don't really matter - it's not a thread forming tool; if you need too much force for (un)screwing, something's wrong with your BB threads (or my thread definition).
Created in Fusion360, using their recipe for creating custom threads: https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/Custom-Threads-in-Fusion-360.html
xml code in the download section, I'm not entirely sure about the numbers, but the plugs fit the BB of my new frame.
P.S.: Just noticed I forgot the ThreadForm tag in the xml. The default trapezoid shape fits in my case, however, you might want to add the ThreadForm tag for WithWorth threads.
