Artillery X1 Lever Arm - dual bearing

thingiverse

EDIT 31-Aug-20; Small revision to add a print in place support for the idler bearing hole, and small adjustment to the tube section to better secure the tube, and improved printability. Thing Details; Updated version of the extruder lever arm for the Artillery Sidewinder X1. Main changes; 1) Dual bearings to run on the motor shaft. Helps to stabilise the arm, reducing wobble. 2) Bearings spaced to line feed tube up better with the hotend feed, which also stops the arm touching the gears. 3) Integrated spacer to negate the need for a lever clip I've included two versions, one that uses 10x5x3mm bearings, and one that uses 9x5x3mm. You'll need two of which ever size. Note; the motor side bearing is meant to stand proud, as it spaces the arm away from the motor. Post-processing wise, you'll want to run a 3mm bit through the idler pulley pin hole, and possibly file the feed tube hole with small round file, as the fit is intentionally tight. Designed to be printed with 0.15-0.2 layer heights, 3-4 perimeters, 20% infill.
