Color:

Latch is extruder designed with speed in mind - it lets you change filament quickly, it provides great grip even for flexible filaments like TPU or BioFlex and flexible PLA. Easy access to the drive gear allow for quick cleaning process.

Suitable for 1.75mm or 3mm filament. Guideholes are big enough to fit 4mm OD PTFE tube so you can chose inside diameter either 2mm or 3mm. Latch was tested with following materials so far:
-PLA
-HD PLA
-PET-G
-ABS
-ABS-X
-TPU (yes... with bowden)
-BioFlex
-Flexible PLA
-IGUS idrylin Tribofilament
-Nylon trimmer line (I tried to push it to the edge!)

Other things you need:
-M3 bolts - (I do not provide lengths since I noticed that different motors have different depth of mounting holes)
-M5x10 bolt to hold the bearing
-625 bearing
-For the pivot points I used 2mm steel rods from rivets
-MK8 Drive gear - 9mm Outside diameter
