M Prime One - Carriage with blower fan

thingiverse

Description Following the same principles of M Prime, I have designed this carriage that allows to put radial fans. These are found to blow more air, which ultimately improves printing quality. It is meant to hold the given capacitive sensor and hot end but replaces the axial fan by a radial fan. This is fixed with a screw and the air is guided with an extra part. I specifically designed this for my fan and the E3D v6 Little but could be used with other standard fans and hot ends. BOM There are three parts: Carriage: which, oh surprise, is the carriage. Hot end holder: the part that fixes the hot end to the carriage Blower commander: designed for 50mm fans and the E3D v6 Little. 50mm radial fan E3D v6 Little 2x M3x20 4x M3x10 How to Follow your instinct. If I did it you can do it too! :P Firmware As the position of the Z probe changes with respect to the hot end, the firmware must be change accordingly to have a reliable autoleveling. My settings are #define X_PROBE_OFFSET_FROM_EXTRUDER 24 // X offset: -left [of the nozzle] +right #define Y_PROBE_OFFSET_FROM_EXTRUDER 4 // Y offset: -front [of the nozzle] +behind #define Z_PROBE_OFFSET_FROM_EXTRUDER -1.0 // Z offset: -below [the nozzle] (always negative!)
