I had few (bad) filaments rolls that broke into small strands inside the bowden tube that leads to the extruder. i’ve decided to feed the extruder directly, bypassing the inner bowden tube.
After testing few prints, i can say it works great!
I’ve added a cone to the “BCN3DSigma – Bowden entry extruder” part and attached it back with the old screw.
I find it’s much more easy and quick now to replace a filament with less friction, less time consuming errors and cleaning… – in short this is as close as i can get to a direct feed.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
