I repackaged the electronics today. I had the electronics all mounted to an acrylic plate, but this will make a little more robust.
I started with a Keling (ATI) basic electronics enclosure for the Gecko G540. It cost about $79 and that includes a power entry connector, a fuse (did not use), a power outlet (did not use), a lighted power switch, an e-stop button and a 9 pin D connector for the limit switches.
I only had to add a cutout for the torch height display to the front. Everything else bolted right in. The only kludgy thing in the drawer is the two 12VDC isolated power supplies. I used wall warts rather than buy two new supplies. The torch height system needs these to stay isolated from the torch.
I did not use a fan. I doubt I will need one and the power supply has one that turns on if it gets hot. with the well ventilated chassis that should stir out the heat.
