Robo3D R1 Hexagon parts fan shroud
Description
Improves Airflow Across The Robo'S Extruder Nozzle To Improve Bridging And Overhang Performance. Designed To Fit Directly On To The Current Generation R1 With Hexagon Extruder. _Should Be Printed With Abs Or Other Materials With A High Gt Temperature_ My Original Design Narrowed Right Down To Blow Air Only Across The Nozzle However Given The Extremely Limited Space This Would Choke The Fan Resulting In Pitiful Airflow. This More Open Design Blows Air Across The Whole Hot End And Is Much More Effective. Bonus Points If You Print It With Thermochromic Material :) ----------- 30/01/2015 - Added Hot End Shield To Reduce Airflow Across The Hot End Without Reducing Airflow At The Nozzle. Tested With Abs@230°C ----------- 29/03/2015 - Reduced The Size Of The Base From 40Mm To 38Mm
