Includes cutouts for wiring and a cutout within the lid so the timer cog can be adjusted with a small flathead. The lid has some protrusions to keep the jumpers from wiggling out.
You will need 4x M3x35mm bolts and 4x M3 nuts. I printed mine in TPU with supports everywhere (only needed for the cutouts for the wires).
