"Dragon Tongue" rigid mount adapter from the Dragon Hotend to the Prusa Bear extruder

thingiverse

**The Dragon Tongue** - can be screwed to the Trianglelab Dragon Hotend V2.0 and used in the place of a standard E3D prusa V6. The adapter allows **_one handed nozzle changing_** due to the Y-shaped "tongue" that fits the extruder cover shape and stops the hot end rotating. The adapter is designed to work with the bear extruder https://guides.bear-lab.com/c/95jghwzvw9l46s3g and inspired by the design for a hard mount link from @SugaryPlumbs https://www.prusaprinters.org/prints/48067-mk3s-bear-rigid-mount-for-tl-dragon-hotend The adapter uses the screws that are supplied with hot end by Trianglelab. **Development:** - current version takes a PTFE tube but not the cuff and clip that holds the tube. **Sources used:** - 3D models for the extruder https://github.com/gregsaun/bear_extruder_and_x_axis - 3D model of dragon hot end https://grabcad.com/library/trianglelab-dragon-hotend-based-on-slice-engineering-mosquito-1 The hotend used is the standard flow version: https://www.aliexpress.com/item/4000404170721.html?spm=a2g0s.9042311.0.0.5ab34c4da2aZI5
