Apple Tv Remote Grip

This started with me attempting to print this model a few times. I tried PLA, PETG and TPU, and i tried all of them with both 0.4 and 0.8 nozzles and could not seem to get the remote to stay in the model. And i didn't like how it required me to fill the entire volume of it with supports.
So i found this model and used it to first sketch around and then as a cutting tool, for the rounded edges. 
I've left about 0.25mm tolerance everywhere except the leading edges of the corners of the remote. 
I am printing this model with an 98A TPU, 1.5mm walls and 25% gyroid infill for it's awesomeness when it comes to TPU squeeze.

Should print fine without supports as long as you aren't moving too slow on the outer lines.
