Greg's Wade reloaded - Guidler, Tilt Screws, Fishbone Gears

PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This derivative of Greg's Wade Extruder collects all the best ideas and latest features and improvements:
* Greg's excellent "Guidler" for perfectly lined up filament feed AND easy access of the hobbed bolt
* Tiltable idler-screws for opening the idler without removing the screws entirely
* 4mm elevation of whole extruder body/bolt/motor mount to allow slightly bigger 9/47 herringbone gears
* 2mm extra bolt-motor-distance for the same reason
* M4 nuts and screws for idler, since M3 screws in more than 60mm length are sometimes hard to source (at least in the common hardware stores of northern germany..)
* Well, 9/47 herringbone gears!
* All nut-traps have been corrected for correct fit (all prusa parts seem to use slightly wrong sizes.. should be 5.5mm wrench size for M3 nuts, I changed all of them to the right ISO values with additional 0.2mm clearance. Fits great for a precisely calibrated prusa)
* Additional hotend-mount option "reprapfaborg" for Stoffel15's great hotends that use 10mm shaft diameter of 20mm length (shown on one of the pictures as a cut-view); you can get one via http://reprap-fab.org
* 8mm thickness of motor mount (instead of 10mm) in reference to wider herringbone gear
I made STL-exports for these three hotend-mounts:
* groovemount
* jhead mount
* reprap-fab.org
My configurations were made for 0.25mm layerheight (using 0.35mm nozzle), so if you're using larger values please change the parameter in the SCAD and export your own STL.…
