Minimalistic Support Free PC4 Couplers (M6/M10)

Minimalistic PC4 Couplers (M6/M10) w/ Mount/Holder

• No Supports Required
• Thread PC4-M6 or PC4-M10 pneumatic connectors on each end to create a PTFE / Bowden tube coupling point.
• PC4 Coupler Holder_Mount.stl is a mount/holder for 4x hexagonal coupler units. 
  • Optional M3x0.50 threads for M3x4 grub screws to hold the hexagonal couplers in place inside the holder.
  • Optional M3x0.50 x 3mm threads on the rear to bolt directly to something or to bolt brackets to it to bolt somewhere, outside a filament dry box or stack of filament dry boxes. 
• OPTIONAL: 15MM Segment of ID2, OD4 PTFE Tube can be pushed into the center of the coupler hexagon for additional protection of the filament inside the coupler. 
• I also use https://www.printables.com/model/466229-inline-pc4-m6-filament-feedretract-coupler when manual load/unload movement is required for the filament.
