This is a very simple cube. It has a chamfer on the bottom and the remaining sides are filleted. When played with, it feels nice in the hand. The top and bottom should be smooth and the others textured. This gives a nice feel.

The flat chamfer on the bottom feels nice with the filet on the top.

It also makes a good test object to try out different fuzzy skin settings, you can see them in the slicer, but feeling them is a much better way to see how they feel and if they are right for your project.

Printing

Use fuzzy skin - the default setting is nice, buy use your own if you have a preference.

• Walls: 2
• Infil: 10%
• Support: None
• Skirt: Yes
• Brim: No
• Fuzzy skin: Outside
• Fuzzy skin thickness: 0.3mm
• Fuzzy skin density: 1.25mm
• Fuzzy skin point distance: 0.8mm

For top and bottom surface, you probably have values that work well for you. I tend to leave the bottom as default, and make the top just a little finer such as 0.25 to get a smoother top. After all, this is about how it feels int he hand.

The blue one is 35mm and for me, that is a little too large, the blue/red one is 30mm and fits nicely. The 25mm is not shown.

If anyone wants other sizes, just let me know and I will upload the files. This works better than resizing the cube, as the edges are just about the perfect size and that changes if you scale.

Material

I have used PLA, but anything you want should be fine. it is only a simple cube, so nothing fancy is needed for printing.

I used a two colour, Blue/Red and the other in Blue. I think what looks best on your desk is the way to go.

PETG and TPU will be nice for this, as they are slightly softer materials in the fingers.
