Raspberry Pi 3B+ Case, screwless, internal clips

**UPDATES**
4/21
- Much improved spacing for the clips (clips are longer and have more clearance, making it much easier to ensure a solid attachment)
- Changed the logo on top to be the RPi logo
- Audio jack port is now round to be a bit cleaner and provide more material to support the clip hole on that side

Just a basic case for a Raspberry Pi 3B+ with internal clips and pegs inside for mounting the Pi. My first attempt (with many iterations) at building a design to fit an existing component.

** Printing **

Supports are recommended for the top, since the clips cannot bridge. You don't need support for the clips' posts, so I usually set my slicer to only print supports for overhangs greater than 60 degrees. Supports for the bottom half are less necessary since the gaps are small enough for bridging, but if you're having trouble with the clips not fitting the clip holes, print with supports. You'll need a small screwdriver or some other small wedge to get the supports out.
