Nema17 Mount for Kossel Mini

thingiverse

The first version (thing:371963) was perfectly working but had some cons. The most prominent is the fact that the screw that hold the extruder to the frame are also the screw constricting the ptfe nuts. This mean that when you remove the tube usually the extruder rest on the table next to the printer and unfortunately for calibration purpose I check the extruder feed rate when I change filament doing this a few time a day start to become really annoying. Than this mount will change all this. The motor and frame mount snap in together securing the motor (just play by putting the bottom of the motor on the bottom leap and gently pushing it will snap in place). Now you motor can be wired and left in palce even when the tube is removed. To remove the tube un-tight(only) the left screw and un-tight the right screw and swivel the constrictor bar toward the bottom. Perso I have now mounted the extruder on the front left beam (X) instead of the bottom beam (Z) reducing the amount time I need to move the printer to access the extruder. Please don't hesitate if you have any question Instructions For the motor spacer to be strong enough you need to print this with minimum 3 shells and over 40% infill any layer height will do but infil need to be strong otherwise the spacer might snap. My settings is 3 to 4 shells 40% to 60% infil
