Adapter bar for a narrower / longer relay board
prusaprinters
I've bought a relay board (https://www.amazon.com/dp/B00KTEN3TM) that looked the same as the original design. It ended up being a bit longer and a bit narrower. I've made a simple adapter bar to accommodate the board. The adapter can be super-glued in place. For an added security, drive a few red-hot pins / pieces of wire through the sides of the bar. You can ignore the divot in the bar - for some reason, I was fitting the board with relays to the left :)
