Reverse Bowden Plug-In Z Top

I use a reverse bowden tube on my MK3, but I prefer to utilize two PC4-M6 fittings instead. Initially, I had printed a z-top with an integrated spot for those fittings; however, anticipating the installation of my MMU2, I decided to print a version from jltx that omits the extra components. Between the planning stage and actually setting up my MMU2, I still needed a means to connect a reverse bowden tube without attaching anything to the frame. Consequently, I designed this device that would simply plug into the hex hole on Prusa printer z-tops. The images display the original orange stock MK3 z-top alongside a black version of this creation by jltx: https://www.thingiverse.com/thing:2779123 Depending on print tolerances, you may need to adjust your print's scale slightly to achieve a snug fit. I opted not to fiddle with it, so I applied a single layer of blue tape and it works just fine. The threads for the fittings are incorporated into the model, eliminating the need for tapping.
