Summary

Warning : this is the OLD version of my geared extruder. You might want to get the new (and very much improved) one, at http://www.thingiverse.com/thing:1359717 ;)


Yet another geared extruder… ;)

This one is specially designed for my SmartrapCore printer, but it can certainly be adapted for other machines.

I made its body in 3 parts that you have to stack together, so it can be printed without using material support. It's really easy to assemble, though, and it allows for a convenient way to attach it to the printer's wall.

It works with a Bowden and a NEMA17 step mottor. The list of extra parts and assembly tips are in the "Instructions" section.

General idea is obviously derivative from the famous Greg's Wade Extruder, and gears are exactly the same, with the very effective good old Citroën chevron design. :)

Update (07/30/2015) : I made minor modifications on the gears…
Update (10/12/2015) : fixed some minor issues on body & latch parts…
Update (10/13/2015) : added body-front and body-back alternate versions for a different installation method in the printer box, that could fit much better the aluminium SmartrapCore.
Update (01/25/2016) : slightly modified small and big gear, mostly by making teeth corners less sharp.
Update (01/27/2016) : modified a few things on body parts (V. 095b) to improve bearings rotation freedom & things like that…
