MK3 BMGBear Extruder X-Carriage (Experimental)

thingiverse

Rev2 - Updated belt channel depth and added slots for excess belt length. ____________________________________________________________________ This modified version of drodfro's BMG x-carriage features the prusa i3 mk3 full-bear upgraded x-axis belt path incorporated into it. It has not been thoroughly tested yet, so proceed with caution. What I accomplished (this was a quick fix since I spent money on the bear upgrade and the BMG upgrade without realizing they weren't compatible... lol): First, I filled in the belt path on the drodfro design. Next, I created a DXF file from the v0.6 bear extruder of just the belt path cuts and imported that sketch onto the drodfro design, aligning it with some measurements taken from the axes of the bear design. Then, I added the bear belt path to the drodfro design with some minor modifications for the screw hole in the middle. After that, I created the chamfers. Finally, I increased the lower belt gap by 1mm as it would likely rub otherwise.
