SpeedDrive v1 - Ender 3 direct drive mount

thingiverse

The post discusses various upgrades and modifications for 3D printers, specifically focusing on improving performance and functionality. Here are some key points: 1. **Dual 5015 Fans**: This upgrade significantly improves cooling performance compared to the bullseye design. However, if printing high-temperature filaments like nylon or PETG is a priority, turning off cooling completely may be necessary for maximum part strength. 2. **Bltouch/3dtouch**: This upgrade provides precise bed leveling but has limitations: it requires an already level bed and doesn't compensate for gantry slop. It's essentially a glorified endstop unless there are frequent changes in build surfaces or the bed is warped. 3. **Files Needed**: Various files are provided for different extruder types, including stock, BMG, CR-10s PRO, Redrex geared, Ender 5 stock and BMG, and Geeetech A10 (BMG/Stock). Optional mods include a Pi camera mount and a clever X-cover with endstop. 4. **Credits**: The design for the V-wheel mount comes from Thingiverse, while bullseye ducts and Hero Me ducts are also sourced from this platform. Special thanks go to u/TianZiGaming for educating on direct drive setups, and various users for beta testing and remixing support. This post provides a comprehensive overview of upgrades and modifications that can enhance the performance and functionality of 3D printers.
