Shower drain

My first project. It's an iterative, learning process, wouldn't recommend it to print it.

Squared shower drain with rounded borders and rounded hole in the center. Dimensions:
- 126x126mm square with 8mm border radius
- Centered hole of 64mm diameter and 15mm depth.

I used tree supports. They take a while to remove, but are needed


--- v3 update ---
- Don't use v2, it can't hold much weight in the center and eventually breaks,
- Implemented a v3 version that can hold weight with a star pattern in the center.
- v3 holes are too small and can't swallow enough water flow. I'll keep iterating.
