Quick little swivel mount for the extruder stepper assembly.
You can use this in combination with a Nimble Sidewinder if you want to keep the max height needed as low as possible.
It will allow the stepper to swivel back and forth easily. You will need a 8mm bearing for this. Use a 608-2RS (8x22x7) bearing. Also included is a little spacer to allow the bearing to rotate freely and not be jammed by the screw going through it.
You assemble it by inserting the bearing and mounting the aluminium extruder bracket. By inserting the screws you tighten the arms of the swivel and that clamps the bearing tight.
