Diagonal Duplo Bricks

I really wanted some diagonal Duplo blocks to further expand build options. The only other attempt I know of is the Strictly Briks diagonal block and I really don't like that one because it is of very limited use.

Test prints done, some minor problems were fixed. I guess having a 15-20° angle would be nice but other than that, these work pretty well.

###45° blocks
There is an adapter to a 45° angle and also an "anti" adapter to go back to regular grid. Should work especially well with the [Bauhaus Duplo #3: Factory Window](https://www.thingiverse.com/thing:3293170), for example.

###3-4-5 Pythagorean triple
This is the other obvious diagonal solution. Again, there is an adapter and an anti-adapter which work in both rotation directions. I also made a "dual"-adapter that should work as both, adapter and anti-adapter.

###Any suggestions?
If you have clever ideas for other diagonals or improvements for the ones included in here, please leave a comment!
