I always wanted such a BIG RED BUTTON!

Slicer files are working for my Ender 3.

The yellow and the black part a screwed together by using four M3x30mm bolts (I used only 2). And as the switch I used a modified one, which I salvaged from an old PC (together with its two M3x10mm bolts). (A similar switch: "PWL-2P1TL-6SASHA Netzschalter, Druckschalter 250 V/AC 6A" link: https://www.ebay.de/itm/PWL-2P1TL-6SASHA-Netzschalter-Druckschalter-250-V-AC-6-A-2-x-Aus-Ein-rastend-1-/401794460876 or https://www.ebay.de/sch/i.html?_nkw=PWL-2P1TL&_sacat=0)

If you need any other information (or file types for customization), just contact me through a message.
