solid state relay heatsink
thingiverse
This is a heatsink I designed specifically for those who have AC powered heated beds. It has been carefully dimensioned to match the NTE part # RS3-1A75-22 SSR, which you can purchase here: https://www.newark.com/nte-electronics/rs3-1a75-22/ssr-panel-mount-280vac-280vac/dp/02H7049?ost=RS3%212A75%2222&ddkey=https%3Aen-US%2FElement14_US%2Fsearch This 75 amp SSR is more than adequate, and with good cooling, it should provide a very long lifespan. It will fit any 40mm fan with 32mm mounting hole spacing, making Noctua fans a suitable option. I recommend machining this heatsink on a CNC router using aluminum or copper as the material.
