This carriage allows you to mount an E3Dv6 or in my case an E3D lite6 hotend to your tantillus. You will have to sacrifice a little bit of X and Y for this though. Final buildplate dimensions are X:70 Y:85 Z:100 I also added an experimental version with mounting points for X and Y endstops, but I havent printed this version yet. UPDATE: I printed the first endstop version, but it doesnt reach the Axis-Ends, will improve soon! Here it is in action https://www.youtube.com/watch?v=cGKqbfPhd0kPrint with ABS in 0.2 layer height and around 30-40% infill. Make sure you have a layer fan, as this part has a huge bridge. Once you finished printing, simply snap off the thin wall on the left. Insert 2x M3 nuts into the carriage's nutlocks, insert the E3D and screw the locker part on with 2x M3x20 screws.
