Easy infinite cube fidget

My take on infinite cube fidget toy.

At first I designed it as print-in-place model, but was not satisfied with quality of top links, which have to be printed in mid air, so to not weld with cubes.

I changed design where cubes and links are printed separately and then assembled.

You need to print:
- Cube 2a x4
- Cube 2b x4
- Link x8

Recommended print settings:
* Filament: PLA, PETG
* Layer height: 0.2
* Line width: 0.4
* Wall line count: 2-3
* Top/bottom layers: 3
* Infill: 25% (or more if you prefer heavier toy)
