Summary This is my current version of a desktop filament extruder which extrudes filament for 3D printers. Video Link: http://www.youtube.com/watch?v=o4F3e6K5Hxk The instructions are included in the 41 page Construction Manual download. There are 30 STL files included in the 7z zip file download. All the white parts shown in the photo are printed with filament extruded from my prior extruder. A separate download file is the motor tune file for the Kangaroo. I have also uploaded a few of the the stl files for review. A BOM is included in the Manual. I am not making this for sale. Others may be doing that. Oh, great folks, thanks for the donations on PayPal: [email protected]
