Greg's Wade reloaded - Guidler, Tilt Screws, Fishbone Gears, Parametric Filament
by dougc314, published
This is a modification to jonaskuehling's version of the famous Gregs Wade Extruder. I am participating in a 18 unit Prusa group build (using TOMs primarily to print the parts!) We wanted this version, but need both 3 mm and 1.75 versions. I noted as others that the filament path wasn't completly parameterized and that the guidler moves in Z. I believe I have solved the issue, you can read my comments, any code changed by me has a //DEC comment. I have printed a 1.75 mm version, and it seems correct. I also mover the guidler so that the three parts (body, washer and guidler) fits on a 100mm square build platform
No new instructions, just fixed the SCAD code. The filament hole may be a bit tight, I reamed mine out with a 2mm (#46) drill.
Version 2 - Some more improvements. I designed a clasp that rides along the 4mm bolts, and allows a 3mm screw to drop into a hole in the guidler, no more slipping off. I also added a throat to the entry of the filament path, below the idler-bolt junction. Hopefully we can feed filament into the guidler with it closed and it won't jam. I also rounded the edge that the m3 screw has to pass over to make it easier to use. The stls have been run through NetFabb's cleanup service. The springs that I use are seat springs for Delta/Peerless faucets.
