Quick release PTFE tube from AMS Hub Bambulab

The standard buffer for AMS on BambuLab printers has a wider hole for the PTFE tube, but the 4 inputs hub for multi-AMS has a 10mm wide hole. So the quickrelease buttons I found did not fit the 4 inputs hub so I designed a proper one.
This button has a 8.8 mm diameter at the pressure point in order to make fitting a breeze. Also the rear of the button is 12 mm in order to leave enough play for the adiacent buttons in case you use more than one.
The inside of this button is 4.4 mm, while the PTFE tube is (in theory) 4 mm thick. BUT, the provided PTFE tube that came with the AMS is thicker than the extra long PTFE tube that came with the multi-hub. Don't ask me, I don't work for Bambulab. Thankfully, this button works for both tubes, though for the shorter one it is a tight fit.
