Single Channel Relay Box

Here is a more robust single channel relay box. I wanted to have Octoprint control the psu of my 3d printer through a relay and found existing single channel relay boxes to be severely lacking. This one has been designed for 3d printing, is heavier duty/thicker, is able to securely clamp the cables down and has a lid that snaps down with clips that don't instantly break off. Supplies Needed:4 x m3 x 10mm thread inserts4 x m3 short bolts for screwing the relay board down4 x m3 bolts for clamping the cables down1 x 5v relay module here: https://www.amazon.com/dp/B00LW15A4W?psc=1&ref=ppx_yo2ov_dt_b_product_details My printing settings:.6mm nozzle.36mm layer height 3 perimeters20% infill The initial tutorial I followed for this was from here: https://www.instructables.com/PSU-Control-With-Octoprint/The box provided in the tutorial is unusable. It's not designed for 3d printing at all and is not able to safely hold the cables or board in the box.
