Dual E3D Extruder for RepRapPro Mendel
thingiverse
The OB1.4 Dual E3D extruder from downeym boasts a simple design that I admired; thus, I remixed it to fit onto the RepRapPro Mendel carriage. This replacement simplifies swapping with the original part as it replaces the entire front nozzle mount of the carriage. Additionally, two holes were incorporated in the mounting cap for a 50mm fan's installation. In an update, airflow was improved through the cold end to the sides, and PLA fan ducts can now be mounted on the side. Update 2 introduced a more straightforward version of the carriage that should work with the newer E3D-V6 hot-end and its embedded bowden coupling (untested due to lack of access).
