BOTTLE RIBBON SLITTER ------------------------------------- A new PET bottle slitter for the PETamentor2. The PETamentor 2 got me 'hooked' on making my own filament. See https://www.thingiverse.com/thing:5435208 It seemed to make a terrible noise cutting the bottle so I thought I would modify the blade to a 'slitting' action rather than presenting the bottle 'square on' to the blade. I felt that a 'slitting' action may also need less force since it has more 'shearing' action like the ground wheels type of cutter people use. FILAMENT COLOURING PEN ---------------------------------------- This 'paints' the inside face of the cut plastic strip just before it enters the extruder. BOTTLE AUTO STOP SWITCH ------------------------------------------ This allows you to leave the machine running unattended and stops the extrusion when the bottle is nearly finished. BOTTLE 'WEIGHT' MECHANISM --------------------------------------------- This 'constrains' the bottle to present itself to the blade correctly.
