prusa i3 bed heater external relay board bracket by kel

Last crawled date: 4 years, 6 months ago

The original bed heater taps its power from the RAMPS board. Using an external relay, I draw the current from the main power supply instead. My PS has additional 12V output so this was quite straightforward. I also use a thicker core cable, so heating speed up further. This simple bracket design mounts the the solenoid relay board just below my PS. Some M3 botls, nuts and washers finishes the job nicely.
