Elegoo Filament Swatches & Modular Holding System

I love Elegoo's PLA color offerings, but I wanted my own swatches to showcase what I personally look for in a filament. 

Here are the design ideas behind these swatches:

1. Gradual height change in the bottom corner to look at held up to the light/laid over other colors to see how the filament interacts at X layers
    
2. Inset and extruded text/features to see how those types of geometry look like on a model
    
3. Thin header for bed adhesion testing and how it looks with cutout imagery, useful for when you're making things and want to see what a mid-print filament change would look like (and also making them easier to grab when stacked together)
    
4. Thin ramp from the thin to thicker section letting you see what layer lines will look like
    
5. Lastly there's a hole in the top left for use with a carabiner or what have you.

You can print the holder in vase mode. If you're clever you can print them in place rather than assembling them afterwards. The tolerances are tight though, so print a few scaled down in the Z axis to make them short and quick to print to test that first.

I plan on making more of these for more filament colors/types as I get them, not just from Elegoo but from other brands. If there's an Elegoo color that I haven't done, I know there's a couple, just comment the ones you want and I can put them together.
