I wanted a simple filament sample swatch box with space for text on each swatch, without it being too large. Unable to find one I really liked, I tried designing it myself using Tinkercad.
The lid can be printed in multicolor, with the words "Filament Samples" appearing on the lid. It should be printed upside down so that the top of the lid gets a nice texture from the PEI plate.
The box works fine as it is, but feel free to remix it to add other features, such as magnets. When you remove the lid, I designed the box so that you can place the tray on top of it.
Unfortunately, I don't have the expertise to create a Fusion360 file for easy customization of the swatches, so feel free to do so. I used Tinkercad to create the swatches. Here's how I did it:
Next, I imported the sample into Bambu Studio and colored the text. The reason for only moving the text down by 0.1 mm is solely to allow for coloring it in Bambu Studio. This results in a completely flat sample. In my samples, I used the "DIN Condensed" font. If you want to use this in Tinkercad, you'll need to download the font as an SVG and use "custom text" in Tinkercad.
