Bowden extruder by Axbri

Last crawled date: 4 years, 8 months ago

This is my own design of a spring loaded bowden extruder. It has an easy to use quick release lever for easy manual filament loading and unloading. It uses a standard 608 ball bearing and a few 3M screws. The spring I use is the same type commonly used for mounting the heatbed on 3D-printers. The tension on the spring can easily be adjusted by adjusting a screw if needed. The design is prepared for installing an optional short piece of bowden tube under the bowden coupling for guiding flexible filaments.
I made this using SketchUp, and I have included the skp-file as well. Feel free to modify if you want.
