For those looking for screw sizes, here's what worked for me: Controller Board: M2.5x4mm Motor Mount: M3x8mm Case: M3x16mm Suggestion for designer: the bottom hole for PSU wires isn't in a good location with this controller, since the connections are at the bottom of the controller. I suspect that this was designed with a different controller in mind originally. I drilled out a hole on the right side to use instead. Just some thoughts. Overall, very effective design. I'm using this add one as well that others have mentioned for drive spindle retention: https://www.printables.com/model/621425-pastamatic-axle-holder. I'm also using on of these clips on the opposite end of the driven spindle for retention as well: https://www.printables.com/model/499110-pastamatic-retrofit-for-better-target-spindle-rete/comments for retention. I posted the same in the Printables version of this item, I hope that's OK.

Great mod. I didn't like using my drill and this was a perfect solution. Works great with no issues.

How did you do the power supply? Is it possible that you can list witch parts you have bought?
