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.
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.
- Remove the various optimized support structures.
- Use M3 nuts for fixation of custom attachments.
- Use M4 screws for fixation of the extruder.
