FroZen Cheese Extruder

youmagine

This is essentially a customized FroZen extruder, modified to fit perfectly with my E3D v6 hotend. Specifically, it was transformed from the FroZen Tight derivative, allowing for more flexibility when tightening, which I no longer need due to a redesign. While modifying it, I ended up punching holes all over it and decided to call it the Cheese mod of the FroZen, a name that stuck - FroZen Cheese. My goals with this mod were clear: - Allow the use of the insert from the pneumatic coupling in the E3D kit for easier removal of tubing during jams. The nut capture method works well, but I found it tedious to remove the tube on my Makibox whenever needed. - Guide the PTFE tube through the entire path within the extruder to prevent filament buckling and twisting, making flexible filaments usable and providing a smooth path. The mod also improved printability without supports or overhang settings (as long as extrusion width is greater than or equal to 1.5 layer height). To use the SCAD file, you'll need trim.stl; alternatively, rename the FroZen Tight stl to trim.stl.V2.1 has modified measurements for the pneumatic insert, which I haven't tested but should work - I simply dialed it down a bit since it was too loose on my current setup. I've left the k2 custom one there by accident, featuring holes for the filament closer to the stepper motor. This was done because my drive gear was pushed in that direction (likely due to over tightening, which also cracked the acrylic), and without this mod, jams occurred during frequent retractions.
