Solid State Relay Mount

thingiverse

I decided to include a solid-state relay in my new printer's bed heater design. The challenge was finding a discreet location where the heat from the bed wouldn't affect it, while also blending in with the rest of the machine. I placed this component on a joint between 2020 and 2040 extrusions for a seamless fit. I'm taking precautions to avoid overheating by not using a heat sink, although the current load may not require one. Still, I figure some heat dissipation is better than none, so I mounted the relay against aluminum backing for added protection. The Auber Instruments SRDD-100 SSR is my chosen solid-state relay model. To secure it in place, you'll need 2 x m4-16 screws and nuts, while attaching the mount to the rail requires 2 M4-8 screws and 2 t-nuts. I opted for set head cap screws, but as long as the screw head is wide enough for the shoulder, any type will work fine.
