MK8 extruder carriage with 3D Touch bracket v2 (CTC Prusa i3 DIY Clone)

A better carriage can be found at https://www.thingiverse.com/thing:3205032. This design has been optimized with the probe aligned directly with the print head. This revised version has adjusted the hot end, shifting it 10mm to the right, which now matches (approximately) its original position. Please note that this setup does not utilize the original extruder components; instead, you will need to remove the aluminum block and angle bracket. You might be able to design an extruder that incorporates these parts effectively. I identified a weakness in the 3DTouch bracket and have uploaded the modified design. Since creating this carriage, my CTC i3 Pro B has been running smoothly with a GT2560 Rev A+ board and Marlin 1.1.8 firmware (configuration.h attached). To utilize the provided configuration file, you will need to download the Marlin 1.1.8 firmware from http://marlinfw.org/meta/download/ and copy the configuration.h file into the Marlin sub-folder, then compile the firmware. My printer functions flawlessly with this setup; however, I cannot guarantee its performance on your system. This information is supplied without warranty and serves as a guideline for upgrading your 'CTC Prusa i3 Pro B DIY.' I am not familiar with other brands of the i3 model.
