Yes. I 3d printed a skimmer lid, hose brackets, some feeder things, cages that go around my drains so fish cant get sucked in.
Here's the demo I printed for your thing. It works great! It's a tight fit but it moves freely and then when you tighten up the bolt it is stuck in place! I'm printed the full size now. I am printing the part that holds the tablet in black so it'll blend in. I only have a little bit of black left so I didnt want to waste it on the test parts.
