December 8th, 2011. Originally uploaded at www.thingiverse.com/thing:14421. Updated with improvements for better attachment to the Ultimaker. Works seamlessly with 100ml syringes. Still utilizes filament as the driving force behind the syringe. New additions include enlarged end stops, ensuring endstops function even when the syringe is attached. The concept inverts traditional methods. Filament pulls the syringe, squeezing material out in the process. For additional images and videos, visit http://www.facebook.com/europerminutedesign. Instructions: Resize shapes to accommodate your specific syringe. Print the syringe holder. Print the end stop enlargers. Secure everything using M3 bolts from Ultimaker spares through pre-drilled holes. Attach all components. Generate G-code without temperature settings. Set a very low extrusion speed. Open the G-code in a text editor and replace "E" with "E-". Modify the filament diameter to increase flow. Alternatively, use M302 in the G-code to enable extruder motor operation without nozzle heating.
