Popup Swatch Box

Overview
========

Initial release of my pop-up swatch box for filament swatch samples. I had been using the [Customizable Filament Swatch](https://www.thingiverse.com/thing:3346069) by [Makkuro](https://www.thingiverse.com/makkuro/designs), and they were starting to get a bit scattered. I ended up designing this container that serves as both a box and as a display rack/stand for the swatches. It also happens to work as a decent fidget thingie.

Sizing
------

Although targeting the swatches that I used, the OpenSCAD file is parameterized to allow for easy use with most any size swatches. Spot testing was done with [Filament Swatch by JimTiffinJr](https://www.thingiverse.com/thing:4670018), and all fit well. (For that swatch size, use swatch_h = 45.5, swatch_w = 102.5, swatch_thk = 2.85, and swatch_corner = 5)
