Bowden Extruder Universal Fit Left and Right 1.75mm Filament

thingiverse

I was looking for a bowden extruder I could modify to fit my needs, but as usual no original files in Solidworks were available, only STL. So here is a quick creation of a good tight fit bowden extruder, with an included .sldprt file. 147 steps per mm are used in Marlin. You will need: * 5 M3 x 30mm bolts * 2 M3 square nuts * 1 608 bearing * 1 605 bearing * 1 MK8 Drive Gear for 1.75mm Filament, a 3D Printer Extruder Pulley with a 5mm shaft Item specifics include: * Drive gear dimensions: 11mm (height) x 9mm (outer diameter) * Effective diameter: 7mm * Shaft/bore size: ø5mm One Pneumatic Coupling PC4-M6 - 4mm OD PTFE Tubing - 6mm Thread is required, remove the O ring before fitting. You can find this on eBay at http://www.ebay.co.uk/itm/4Pcs-XYZ-Da-Vinci-Pro-3d-Printer-Push-PTFE-Tube-5mm-Thread-Pneumatic-Fitting-/302038047425?hash=item4652dedac1 If you remix this or make alterations, please upload them back with all original Solidworks files so that everyone can use them. This way, people who don't have Solidworks can benefit from the modifications. Thank you for your consideration. I always add the original creation file, not just the STL, so if people want to play with the design they can.
