3d model description

Not your mother's extruder! Kidding... This simple yet very effective extruder is the brainchild of some members of the QR's community (Shauki, Exilau...s & Dale Dunn). I just tried to put it in a pleasant form. The name comes from the ring that looks like an aureola and it uses a coil from a lighter.
This is an original design of an extruder that has the following features:

- Symmetrical load on stepper axis;

- Adjustable filament pressure without spring;

- Simple & open design (easy to see what's happening inside);

- No need for a geared reducer, direct drive;

- Support flexible filament (anti-buckling support on both extrusion and retraction);

- Best bang for your buck;

For details about fitting the coil on the stepper motor, you can find them by looking for #bicgear , #saintflint or #flintfeeder on Google Plus.

05-09-2015 Uploaded some variation on the current design, namely:

- MK8 gear based version

- NEMA14 based version (uses smaller 625 bearings). This last version should perform very well as a "suspended" extruder on a delta with a short bowden. Very light yet powerful enough to get along with the speed.
