Geeetech MK8 dual extruder plate for my Quick Fit Carriage

thingiverse

A mounting plate for the Geeetech MK8 dual extruder made for my Quick Fit Carriage (http://www.thingiverse.com/thing:1670305). The fans and heat sinks have to be removed to fit the plate (they reduce Y-building volume by ~29mm and increase weight and torque of the carriage). Alternative cooling of the throat and the two motors is achieved by a air-duct system powered by a 50mm blower. On each side mounting holes for M3 screws and nuts are present to allow for fixation of bed-level sensors. These holes have a separation of 26mm. I made the blower-attachment removable. I'll add a 40mm fan version later. Used dimension of the mounting bracket: 86.0mm x 10mm x 15.5mm. Because I do not have a dual extruder, I cannot check if everything is OK. There are no CAD-data-sheets available for the extruder. Thanks to Tombhunter for manifold and valuable bug-fixing input. Print Settings Notes: A version with and without manually designed support is provided. Please select proper printing orientation: The flat side is down. The manually designed supports indicate proper printing orientation. Post-Printing Remove the various optimized support structures. Use M3 nuts for fixation of custom attachments. Use M4 screws for fixation of the extruder.
