Infinity cube

Not wanting to wait for the delivery from Aliexpress I searched for a design to print. Found that one from FLA_Labs and liked the idea. But I don't like fillets by design (chamfers get rounded some anyway) and also the thin outer hinge eyes (please correct my terminology...) so I recreated it from scratch. FreeCAD file is mostly parametric by changing the DynamicData (dd) variables. The STLs provided are for a 20mm single cube size and 5mm wide, 3mm thick connector.
You will heed 4 normal cubes, 4 mirrored cubes (any slicer should have that function) and 16 connectors. I printed mine in groups - 1 cube, 2 connectors.
Check [Vertical-Joint-Flipped Yet Another Fidget Infinity Cube v2](https://www.thingiverse.com/thing:4741857) for another way to connect the cubes. The second one (blue/yellow one is assembled like that)

Added Trapezoidal piece for recreating the [Cut Kobayashi Fidget Cube (Infinity Cube, parametric)](https://www.thingiverse.com/thing:3884939) design.

Please any c
