Four channel solid state relay case

thingiverse

I use <a href="https://www.thingiverse.com/thing:4746515"> the custom electronics case</a> for my Ender 3. It has two places for a single channel relay module. For over a year this relay modules worked fine and one of them stopped works some time ago. The light control relay module works now. I had a 4 channel solid state relay module. Each channel of this module allows a current of 2 A. But module does not fit into the electronics housing of printer. I connected the channels of the solid state relay in parallel and designed an enclosure for install relay outside of printer electronics case. Keep in mind that the relay casing protrudes beyond the dimensions of the profile to which it is attached. (My printer is mounted on TPU feets ) I use two M5 TNut for mount relay case to profile and four M3 inserts and appropriate screws to mount case cover
