thingiverse

This is a direct-drive extruder for Jubilee, my toolchanging 3D printer. # Feature Breakdown * Direct-Drive ensures hassle-free retraction. * The design is compact. * It parks into the parking post on Jubilee's Toolchanging System. # Shopping List All stock parts for this extruder can be found on the second sheet of the Jubilee Shopping List. Note that it is listed for an order of 2 extruder heads. # Print Settings Print all parts in the displayed orientations with these settings: * 0.2mm layer height. * 6 perimeter layers. * No supports are needed. **Exception:** print the v-groove locking plate at a 0.1mm layer height. **Exception:** print the fan shroud with supports. # Laser-Cutting Settings Cut the compression_flexure from 0.125-in. Delrin. # TODOs The fan shroud needs improvement for better airflow, so high-speed perimeter printing (beyond 90mm/sec) is currently limited by part cooling. Extra small features should be printed around 30mm/sec. # Updates: * Oct 5, 2019: First pass at updating the fan shroud.
