(Update 2015-08-20) Added 12mm Prox Mount as well.(Update 2015-06-18) Corrected some alignment issues in the carriage and idler as well as changing the proximity holder/idler to use M4 screws as it seems to be easier to get longer ones. Added the Gears in the list as well. I have modified the Adapto X Carriage LM10UU to fit the E3D-V6 Universal 1.75 Hotend. This modification features a mounting block which should fit nice and snug to hold the hotend in place but allows for easy removal, as well as an extra mounting hole for installation of a proximity switch holder, and tab to pick up a opto endstop Also included in this post is the .stl for the Idler, opto endstop holder, Proximity switch holder, and the mounting block. Adapto is a simple straight-forward 3D printer build and can be found at https://github.com/rotorit/Adapto OR http://reprap.org/wiki/Adapto If you like what you see please feel free to leave a tip: http://modernwebsitesolutions.com/resources/tipjar.html
