Threaded PTFE Couplers 2x/3x

I created these double and triple Y-Couplers for PTFE Tubes to work with the standard pneumatic couplers so I don't have to switch the PTFE tube between external spool, my drybox and the AMS. It has slots vor 4x2 magnets in the back so it can be hung up on the back of printers with magnetic back plates like the X1C. The dual version can house two magnets and the triple version three magnets.There are four versions in total. Two for a two to one connection, and another two for the three to one connection.Each coupler has M10 or M6 threads. The inputs are always M10 because you need to push a piece of tubing far into the coupler to minimize friction. For the outlets there are a version each with M6 threads and one with M10 threads for people who only want to buy one set of pneumatic couplers. During assembly it is crucial to push the PTFE tubes all the way through the pneumatic couplers. At every M10 coupler there is a groove in the model in which the PTFE tube should be pushed all t
