The Edifier S350DB speakers are fantastic, however the design for their remote control is woeful. It's a circle. It's the most awkward remote control I have ever used and it's super hard to orientate the IR blaster section towards the speakers when trying to use it. I decided to make it better with a 3D print and this is what I came up with.
The funny thing is, this was my first attempt, and after measing it with calipers designing it in Fusion 360, the remote fit perfectly snug into the cutout without any need for adhesives. It's also very easy to remove if needed.
No supports required. Enjoy.
EDIT: I added a second file which can be placed over the top of the cutout for the remote. It just finishes off the whole design nicely.
