E3D Insert

A Custom Filament Guide Insert for E3D Extruders. I designed a Davinci to E3D conversion, but loading the filament proved frustrating due to the Bowden PTFE connector on my knockoff extruder. To simplify this process, I created an insert that eases loading difficulties. The cutaway picture clearly shows how the throat tapers from 5 mils to 2 mils, making it effortless to load the filament. Print Settings: Printer: Repetier/Davinci with E3D Extruder Rafts: No Supports: No Resolution: .2mm Infill: 20% Notes: The insert prints upside down on my bed without rafts or a brim, but it's on the edge of requiring some adhesion assistance. I've printed with both ABS and PLA using a PLA insert and have encountered no issues. This custom filament guide is specifically designed for knockoff extruders featuring PTFE tubes to prevent filament freeze. To accurately size the length of the tube, I screwed the insert in without the tube, calculated its total depth, and then cut the tube slightly longer than necessary. The PTFE tube simply needs to fit snugly into the end of the insert, preventing side-to-side movement. Now, loading the filament is a breeze – just position it within the 5mm opening and push it in.
