Power Cord and Switch + SSR enclosure

thingiverse

This is a housing designed to accommodate a commercially available IEC320 C14 socket/switch/fuse combination and an SSR (Solid State Relay). It mounts securely to a 20mm wide T slot or V slot rail. The housing features an internal partition that helps separate the "Low Voltage" section of the SSR from the "High Voltage" area at the other end of the SSR, as well as the back of the switch/fuse/socket assembly. SSRs produce heat! To print this enclosure successfully, use ABS or PETG. However, even with these materials, this design may not work for certain applications involving an SSR. Exercise extreme caution and carefully test it first. The IEC320 C14 term is technically correct for what many people refer to as a "PC Power Cord" or a "Standard Instrument Cord". If you're a gadget enthusiast, you probably have several of these cords lying around, suitable for 120V (USA) or 220V (Europe), and other voltages. This design is created using OpenSCAD software, allowing it to be easily modified to accommodate slightly different sized assemblies, alternative exit hole placements, and more. I wanted the Low Voltage control wiring to enter from the right side, the "mains" power switched from the switch exiting the top (hence the hole in the lid), and the "mains" power for a heated bed (controlled by the SSR) exiting from the left side. These requirements influenced the placement of holes and the orientation of the SSR. You can flip the SSR, re-arrange the holes, and modify the internal partition to suit your specific needs. The prints appear fuzzy in photos, but they look perfectly fine in real life. The camera adds a 10-pound illusion!
