last file update: 11.04.2015 A multipurpose Extruder for 3.00mm filaments. You can use it as bowden or direct extruder. You get a really precise description for our extruder here: http://wiki.stoutwind.de/doku.php?id=stoutwinds-rampage-universal-single-extruder The extruder development and creation of the description/build information took several weeks and more than 300 hours (including research, development, sorting, photo shooting, rendering, texting, validating, ...) . It's build from ground up, inspired by Greg's wade reloaded extruder and many similar constructions. It has optical identic features but when you look inside you will see many differences and bonus/comfort features. It's worth to look deeper into. In the gallery you can see different compability examples for E3D-v6, Hexagon and Sunburn hotends. You can install each type: Rampage works with a lot of well known printers. Because the flat base of Rampage has two long variable hole slots you can mount whatever you want. Please see also "instructions" page for some more details about production/usage. For Download just use the latest zipped version. 1.12.12 also includes a pre-placement of parts (for the lazy guys) Nominal filament diameter for good extrusion: min 2,4mm up to 3,2mm; if you need more space for bigger filaments just drill out a bit recent updated files include manual!You can read the complete guide for our extruder at the given link: http://wiki.stoutwind.de/doku.php?id=stoutwinds-rampage-universal-single-extruder for english readers there will be an english translation soon.
