QU-BD MBE Bowden Experiment-1 - ord bot mount
Description
This (**Untested**) Design Has 3 Printable Parts. These Can Be Used To Convert A Stock Qu-Bd Extruder To Use A Bowden Tube. Note That This Is An Experiment. I Currently Do Not Have Any Mount For The Drive Portion, Once I Get It Working I'Ll Work That Out. My Goal Is To Get 2 Print Heads As Close As Possible Mounted On The Ord-Bot. I Believe I Can Get Them Closer By Removing The Drive Motors (Thus Bowden) At The Moment I Do Not Believe I Can Use The Body Block From The Mbe. Those 6Mm Tapped Holes Are Probably Too Close Together. This First Draft Is Intended To Help Me Debug The Whole Bowden Concept **Non-Printed Parts:** * Qu-Bd Mbe Extruder Kit * Straight Quick Connectors Pneumatic Fittings 4Mm X 1/8" Pt Male Thread (10 For 7.26 On Ebay @ Http://Www.Ebay.Com/Itm/321061698459 * 1M Ptfe/Teflon Tubing/Pipe Od 4Mm Id 2Mm Tubing - (1M/$5 On Ebay, Search "Ptfe 2Mm 4Mm") * 1X 624 Bearing (Ebay 10/$5) * 3X M3 Screws To Mount The Drive Parts To The Stepper Motor * M4 Screw For Bearing. (I Printed The Lever/Bearing Hole A Little Small So I Could Use A #4 Screw) * Spring (I Had One In A Box, It Was The Diameter Of A Pencil, And Around 1 Inch Long. I Think I Got It In A Kit From Home Depot) **Update 10/9/14** I Have Been Printing With This Setup For Over A Month. I Am Using The Water Cooled Hot End From [Thing:280314](Http://Www.Thingiverse.Com/Thing:280314) Instead Of This Air Cooled One, But I Would Expect Similar Results. I Consider The Bowden Setup A Success (Had To Increase The Retract Compared To A Virgin Mbe To Eliminate Stringing.) At This Point I'M More Interested In Perfecting The Water Cooled Extruder So I'Ll Post Further Updates There.
