Ender3 自動電源オフ装置　ダイソー節電タップ固定具

thingiverse

Here is a device designed to automate the shutdown of an Ender3 3D printer. It consists of two DIY parts: a Daisy chain power strip and a simple extension cord. The printed plate slides onto the printer's rail, securing itself in place with screws. A mechanical switch cuts off power by moving the Z-axis, similar to the setup seen in the video linked below.
