Printruder II
Description
After the success of my first printable extruder design (the Printruder, see http://www.thingiverse.com/thing:958 ), I wondered, if there would be an even simpler and better design for a Printruder. This is what I came up with. Please note, that there are two flavors of the main part ("Motor Block"): <ul> <li><b>Motorblock_v7_TimerBeltPulley.stl</b><br><i>This design is for use with the standard timer belt pulley, which comes with the MakerBot Extruder MK3/MK4.</i></li> <li><b>Motorblock_v7_WormGearPulley.stl</b><br><i>This design is for use with a 10mm worm-gear style pulley</i></li> </ul> You only need one of both. Be sure to print the correct one! The PCB holder parts are optional. There's a post on my blog on this with more detailed information and step-by-step build instructions: http://pleasantsoftware.com/developer/3d/2010/03/08/printruder-ii/ In order to mount the Printruder II in a MakerBot, you might want to print also a pair of Printable Extruder Holders: http://www.thingiverse.com/thing:1912
