I have remixed Prusa i3 MK3 X-Carriage with Titan Extruder by g_tobet to the new R3 version.
Extruder_Body_R3.stl is for original E3D Titan or clone with the same dimension between holes as original one.
I have also made version for those who want to use standard M3 nuts instead of DIN562 M3. Just chose files with M3 in name.
I have also made small changes with Carriage for easier assembly.
There is .step file for those who want to make changes by yourself.
If you have any questions or there is any unclarity feel free to contact me or leave a comment.
I am using this type of titan extruder and I am super happy with it. Don't forget to change e-steps in firmware.
/ PETG except nozzle-fan-45deg.stl should be in ABS
Lenght of PTFE tube should be approx. 64-65mm
