Propane accessory plug, magnetic

I like the design and ideas of the Propane Bottle/Torch Plug by Sorry_Human_Bean. Unfortunately, the magnets used are very unique and specific. I wanted to use common hobby magnets that I had lying around the house. I also did not want to have a hole in the middle of the plug, which could allow contamination to enter. I plugged the hole and enlarged the magnet cutout to accommodate a standard hobby button magnet that is 18x5 mm (DxH), a common refrigerator hobby magnet. The magnet is fully enclosed in the 3D print.

This does require more advanced print settings and modifying the G-Code, similar to switching filament colors in the middle of a print. I paused the height just before it fills in the magnet cutout. Place the magnet in the cutout and continue printing. In Cura, if print settings are set at 0.28mm layer height with a 0.4mm nozzle, it is approximately layer 22/23.

Of course, you can skip the magnet altogether and just have it print a nice propane accessory plug to protec
