I have a pH electrode hanging inside the aquarium but it was way too loosen. It didn't look nice and it was quite annoying during cleaning time. So I thought it would be interesting to design something useful to solve this situation.
Along with my collegues, we used CADENAS PARTsolutions software to shape our model.
Printed with MakerBot Replicator 2. The pH electrode holder is made a little bit thicker to be stronger and more durable due to its continuous contact with water.
It works perfectly, Enjoy!
