Extruder Case (Air Cooled)
thingiverse
Due to high forces to be applied to my extruder i decided to use a full metal version. My part combines extruder and motor. In addition it's also suitable to support a (60x60mm) axial fan for cooling motor and filament. All can be fixed with M3 screws. https://www.amazon.de/Reprap-Bulldog-Bowden-Extruder-Filament/dp/B01FD1K3GQ/ref=sr_1_8?s=ce-de&ie=UTF8&qid=1496173778&sr=1-8&keywords=Metal+extruder (Update 20.07.2017) With version1.5 (bowd_extr_mainv1_5.stl) I have improved the main airflow channel and also closed gaps where they are not required. Also the M3 nuts are now automatically fixed and hold in position (for easy filament and fan change). (Update 08.08.2017) With (bowd_extr_mainv2.stl) I add a small peace of "air channel" to enhance the cooling and route the air. Especially designed to fit with my Filament system.
