This is an aquarium lighting fixture. It is made to fit for my Fluval Chi aquarium but should fit just about any aquarium with a glass pane around 4mm (or bigger you would have to file the clip after printing). There is a little rim in it in which you can glue a 2mm thick acrylic pane to protect the electronics from any damp/moist. I have fit 24 white LED's on 4 LED strips inside it and they illuminate the aquarium nicely! Just be careful when printing as this print might stick too well to your printbed. I broke my glasspane trying to remove it... But still it came out nicely at 0.25mm layer height, white ABS. For my it took about 3 hours to print (80mm/sec infill and 65mm/sec perimeters). I printed it in about 15% infill which is more than enough strength-wise. Have fun with it, I uploaded the Solidworks 2015 file for those that would like to modify it!
