OpenBuilds Extruder

thingiverse

2018.02.15: Updated short_inductive version. This setup is designed to fit a 3mm inductive probe tightly near the extruder. Make sure not to run your extruder wires close to the sensor, or you will get consistency problems. 2017.01.16: Uploaded the updated version. Same extruder, same gears but I reduced the filament path as much as possible so when the filament leaves the hobbed bolt, it travels 25mm before hitting the extruder. Any shorter and I'd have to redesign the guide rail. 2017.01.15: Updated latest version. I had uploaded the wrong rev which had the filament slot too small and not enough room for the guide rail bearing. Sorry about that mistake. Note: Filament tolerances are tight on this extruder. If you use cheap 1.75mm filament that's out of spec it might jam up. The tradeoff though is that flexible filament works easily. This geared Wade's extruder is designed to bolt directly to a piece of openbuilds 22mm v-slot extrusion. This project started as a remix of the Wade's ultimate extruder, but I'm not great at OpenSCAD so I rebuilt it entirely in Tinkercad and took it from there. You'll need some 24mm hex head screws and T-nuts to mount this to your extrusion. Hotends mount directly but I left the JHead slot plate holes in case anyone needs that for accessories. This is for a custom printer I'm building from all openbuilds materials, ignore the damaged octagon hotend. It's just there for fitting purposes. Print Settings Printer Brand: Ultimaker Printer: Lulzbot Rafts: Yes Supports: No Resolution: .2 or smaller Infill: 15% or greater Notes: I use ASA because it's fantastic, but I tried to make as many surfaces rounded as possible to try to make PLA a bit more friendly of a print.
