Updated some prints and water change

Finally got around to doing my second water change. The process is super simple and only takes me about 10 minutes start to finish now. I lay out my water hose and extension cable, hook up the pump to the top-off valve, and then I open up the drain on the return pump. As the water goes down in the sump, it trips the top-off which sends fresh salt-water from the tank outside. The temperature drops about 1 degree with the temperature of the water from the outside storage.

I also finally got the power supply controller printed. It took a couple of re-designs to make everything print. I think part of my problem is that ABS shrinks and also that my printer prints a little on the small side (about .5 mm per side on a 20mm print). I still need to calibrate my printer’s axis.
