Ender 3 Direct Extruder mount for dual geared Extruder (CR10-S pro style)

thingiverse

Update as of November 2020 I've added an aversion with upshifted 5mm boltmounts and flatbottom. This enables it to be mounted on the linear rail x-axis mod https://www.thingiverse.com/thing:3474395, along with the drilltemplate https://www.thingiverse.com/thing:4496685. However, I realized too late that this template is not correct. The holes are about 8mm too high. I had to drill new 5.5mm holes for my modified mount. Update as of March 29 2020: It was evident from the pictures that the hotend on my Ender 3 had a 2mm offset to the right, leading to a slightly crooked bowden guide from the extruder to the hotend. I've done some shenanigans in meshmixer and combined it with some basic OpenSCAD wizardry to create a second version that's 2mm offset to the right. This allows the bowden to be fed straight into the hotend. If you're facing the same issue, please use this one (adapter2_shifted.stl)! I've remixed another version of the beloved direct extruder mod mount from @benawhite to adapt for the new CR-10S style dual geared aluminum extruder. https://www.aliexpress.com/item/4000177086141.html The existing remixes didn't fully consider the spring tensioning screw. With my mod, the screw is fully sunk into an 8mm hole. By removing only the corresponding stepper holding screw, you can access the tensioning screw to change spring tension without disassembling the entire mod. For attaching the stepper motor to this mount, 2 M3x25mm are needed. Please be aware that these are longer than the originally used ones. Print adapter.stl with 3-4 perimeters and 100% infill at a 0.2mm layer height. If you want to modify it, copy all files into a folder and open the OpenSCAD file. It imports the original mount and makes the changes. Render and save to a new STL-file. The same applies to the 2mm offset version. You need all regular files in the same directory to create the offset piece. Have fun!
