3D Printed Dual Relay Board on the DIY QU BD TwoUp Printer

In this episode of DIY 3-D tech.com will look at building a 3-D printed board for dual relay controller. As part of this we also have to use care is this relay board will switch line voltages so if you notice we’ve left the bottom on the board to protect and insulate from this. It’s also worth noting that conductive plastic should not be used print support boards for electronic components. In addition if you’re interested in finding out about this board you can get more information at this link (amzn.to/1KTA5nQ)
