Greg's Wade extruder for Prusa i3
by misan, published
Two things have been changed from regular Greg's, one is the motor location, that has been translated, and the whole thing has been elevated over the base so elements protruding to the back (towards the x-carriage) are now above it.
It fits the standard x-carriage of Prusa i3 (30 mm version, which is the latest).
Based on dviejo's mod.

I design with cad programs that are visual and even though I can program scad drives me insane. Oh, well, thank you.
M4 screws won't fit. Not sure about what separation between them in the plate. But if you match them in screw size and distance between centers (30mm in here) it should work.

A pair of M3 bolts (30mm or longer) will be needed to fix the extruder to the x-carriage.

I am using a pair of 50mm hex bolts, with springs and M4 nuts for providing the idler pressure.
I am told (thanks obijuan) that for 48mm body-long steppers you want to add 5mm to base_extra_depth value on the source to get additional clearance.
If you need extra clearance but you already printed the extruder, or if your x-carriage is 24mm instead of 30mm, you can use this part to fix any these problems: thingiverse.com/thing:81539
