Inspired by TwoTimes awesome wobble arrester,

thingiverse.com/thing:2151

You will need to purchase the vertical rails and bushings listed in the wobble arrester materials list.

The design captures the Z-axis nut, have a smooth base which can slide smoothly under the acrylic and have a vertical pin to prevent rotation. it is all very simple and makes a huge difference in the smoothness of your prints because it removes the wobble from the rotating z-shafts.

I also printed a simple triangle to capture the z-rails, but the ones in the wobble arrester is far cooler.

Still in the draft stage but the best extruder I have used yet. Two opposing motors. this give a rock solid grip on the filament.

Next revision will be making a tighter fit on the empty space around the pulley on each side.

You may need to addjust the screw holes for the motor, if they get too tight the filament wraps like crazy (don't ask how I know)

Future will see this design refined and printed on the CupCake, two pieces, the one side will hold a motor including entry /exit for filament and hold the nozzle. The other side will dovetail and slide so the motor pulley can be adjusted for tightness to the other pulley, Im thinking it should have a bolt in the direction of the motion with a wingnut for adjustments. See sketch.

ANYONE please feel free to design that mount, I am not terrible good at setting up parts with accurate screw holes etc. :-)

"Type R" as in BMW motorbikes, two opposed cylinders slightly offset.

This is a simple pressure fit lenshood for the Leica D-lux4 and Panasonic LX3.

Lasercut project for a small lens-hood for the Sanyo HD1 and HD2. It is pressure fit on the lens.
