Inspired by the design of sarman_1998 I created my own version which can be used in combination with PC4-M6 (and PC4-M10, see below) fitting PTFE tubing (6mm thread), and 2 M3 bolts + hexagon nuts.

The code can be changed to choose your own degree (or place a comment, and I will add a stl)

Items I used: bolts: M3x10 DIN 7985 (cross) -> as long as it is flat at the side of the thread washers: DIN9021 3,2mm washer (optional) nuts: M3 DIN 985 (nylon locking nut) -> outside measures: 5.5 mm (parallel sides of hex), height 4.0 mm (2.4mm hexagon)

I decided to place the center of the holes at a fixed distance of 15mm from the tube-hole (so 30mm between both holes) to make it easy possible to replace them - if I need to do - for another design as long I keep using the same distance.

Thanks to motocoder also a template to drill the holes is included.

2018-09-03: Added a PCx-M10 outside for 10mm connectors, on request of bratej

2018-11-11: v1.1: Improved calculations for the position of the thread, relevant for an angle between 40° and 60°. Thanks to Arnaud.
