I wanted a way to not have my 3018 CNC's controller just laying around. so i modeled this mount for it that also includes a hole to put a button into that can act as a emergency stop. you will need a M5x10 screw/bolt and a M5 nut that fits into the aluminum extrusion (my cnc came with a spare nut). you will have to wire up the button yourself with some small wire and heat shrink tubing unless you buy the buttons with the wires already attached. these are the buttons i used: [https://www.amazon.com/Gebildet-250VAC-Prewired-Momentary-Railway/dp/B07YDHP3HS/ref=sr_1_4](https://www.amazon.com/Gebildet-250VAC-Prewired-Momentary-Railway/dp/B07YDHP3HS/ref=sr_1_4) (you can most likely use any 7mm button).
