Galaxy 1 Relay Mount

thingiverse

This is a mount to replace the single relay board with a dual relay board that will allow the resin pump to also act as a drain pump by reversing the polarity. The soldered pins on the bottom of the relay board would touch the screw mounts of the enclosure, so I needed a spacer. This part requires two additional 3mm x 12mm long screws. The four old screws the mounted the single relay board are also reused. Two of the holes for mounting the new relay board are also threaded, it seems to help but probably not needed.I have not tested the final design as the previous is working well enough. I found there is a small difference in the mounting dimensions of the single relay board and the dual relay board. The first one I made, one of the holes was too far apart (.25mm) and wouldn't line up. If using a different relay board, this design might have to be tweaked again...Relay boards: https://a.co/d/bPxaT4X
