Universal joypad stand

This stand works for pretty much all controllers I found: **Switch**, **Stadia**, **Steam**...

**Features:**
- Will not fall down easily when placing the controller.
- Has optional bottom bumpers.
- Prints in place with little filament.

**Printing:**
- I've printed the main stand in PLA with 0.2mm layer height, 2 walls, 10% infill (using less than 30g filament), no support.
- The bumpers below are optional and meant to be printed in TPU with 1 or 2 walls, and 5% infill (very little to remain as springy as possible). They fit in place, or can be glued with CA.
