This is a m10 threaded version of the sv06/plus bowden connector. Definitely made it in tinkercad, doesn't need to be pretty, just needs to work, and I can confirm that it does. This is a remix of the version that needs an m6 bowden. I did not have any of those and instead of waiting for an amazon delivery I made what I have work. This is centered on the hole from that model and has a very nice, straight, path to the extruder so you do not wear out the top brass piece on the extruder. It can be printed in anything you would like, I personally used PLA and it is perfectly fine.
The author remixed this model.
