About this 3D model

It's a direct drive Bowden extruder for the MK8 drive gear. It supports both 1,75mm and 3mm filament. Just change your pneumatic fitting (all M5 fittings will fit). There are 2 versions: MendelMax version will slide into your aluminium extrusions. Standard version is for all other printers. The Hotend mounting plate will both fit into standard x carriages as well as in my Quick change X Carriage (http://www.thingiverse.com/thing:130881). It's designed to be very easy to use and to change filaments but it also offers great stability.
