4 in 1 out multi filament upgrade M5, M6, and M10

These models are based on SilasPfeifer's 4 in 1 out multi filament upgrade M5 design.

M5x0.8 pitch is a remix of the original.  The remix was to provide a better M5 thread  profile as I had issues with threading in the PC4-M5 pneumatic fittings straight.  

• FDM print at 0.1mm layer height.
• SLA print as needed.

NEW M6x1.0 pitch is the same body at the M5, but for PC4-M6 pneumatic fittings

• FDM print at 0.15mm layer height.
• SLA print as needed.

NEW M10x1.0 pitch is slightly larger and designed for PC4-M10 pneumatic fittings or www.hotends.com Bowden Aglet's with 6mm of PTFE tube past the Aglet for the input side. Use a PC4-M6 pneumatic fitting on the exit side.

• FDM print at 0.15mm layer height.
• SLA print as needed.

Printing Position -

FDM - Position the square between the four inputs on build plate.  Use paint-on supports to keep support material form going into the threaded holds.  Use “build plate only” supports. Printed with 2 perimeters and 15% gyroid infill. 

SLA - Position one of the flats from one of the inputs flat on the build pate.  Let your slicer raise the part off the build plate and apply supports as needed, keeping all supports out of the threaded holes.

Material - 

FDM - 

• PLA, PETG, ABS should work well.  Expect PETG and ABS to out perform PLA.

SLA - 

• Elegoo Standard Resin will work, but due to being on the brittle side, the part lasted only a couple of months
• Siraya Tech BLU - currently printing so it can be tested.
• Siraya Tech 80% BLU / 20% Tenacious - currently installed on printer for testing.
