kbricks figure

I have received many requests for adding a figure to the [kbricks construction system](https://www.thingiverse.com/thing:3574234) so here it finally is! The new kbricks figure is compatible with the other parts of the construction system and it comes in two sizes, **tall and short**. You may even combine the two sizes, e.g. long legs with a short body or the other way round, and with long or with short arms. So there are all kinds of variarions - just like in real life ;-)

This [video](https://youtu.be/9OwKBPvL2ME) illustrates how to assemble the kbricks figure.
