Filament spool base anti-roll

I decided to create a base for my spools for display. The spools are in a vertical position.

You can print with your settings. One model should take up to 25 grams of filament, but you can change the infill and wall number.

You can print each material to also display it and show it to customers (texture, color, feel etc.)

It is a good way to spend the rest of the spool, but keep in mind that your filament can suck the moisture from the air.
