We are launching a filament extruder in about a month on Kickstarter. We are Open Source and would like to collaborate if possible on the Strooder. Our design is longer and has a self-winding spool. Its made to use in a lab or school, meaning you can extrude what you need, or make a full spool if you'd like. After Kickstarter orders are fulfilled, we will release the files and BOM. https://www.kickstarter.com/projects...token=b04cde69
