Prusa Air 2 X carriage - Micron direct drive extruder by Phil_Maddox

Last crawled date: 2 years, 12 months ago

Got asked by a friend to see if i could work something out to fit the Micron extruder on a Prusa Air 2
Have taken my earlier X carriage design http://www.thingiverse.com/thing:154258 and re designed the top carriage plate to accommodate the micron extruder and still maintained the standard 2 holed spacing for other extruders ( Gregs wades etc)
This is concept Rev 1 and seems to work great. Although with the fan at the front it is difficult to see what is being printed and next revision will attempt to relocate the fan.
The micron direct drive ( geared stepper) and hot end is such a great piece of engineering it just had to fit somehow. The compromise is that the X axis only has 150mm of usable travel but that is a small price to pay , On the prusa air 2 using this extruder increases the build height to 125 so effectively what you loose on the X axis, you gain on build height.

Update March 1st >> Rev 2 Added a duct so the fan can be mounted to the side under the stepper motor. Much better view of the print during printing. Fan duct contains an M4 nut trap that is aligned with the adapter bracket hold down bolt
