Something a little more fun for use as a test model or colour swatch model.

Use as colour swatches or test prints. Keep and put them together as a tiled plane.

Now Included: a smaller, thinner version, that you can use for a quick flow check of a new filament. Less that a gram of material and should print in a couple of minutes. It's on a 40mm hex spacing, and only 3 layers (0.6mm) thick. Should still tile if you have elephant's foot under control.

Pieces are designed with a clearance of 0.3mm (the tile is 0.15mm smaller than a perfect fit) - which makes it a very tight fit for my printer.
