Simple twisted knife block

This is a simple twisted knife block.
It can hold:
6 knifes with 23x2mm blade
3 knifes with 35x3mm blade
2 knifes with 23x2mm blade
1 knife with 43x3mm blade
1 knife with 30x3mm blade

the outer diameter is 159mm and its 205mm hight. The cutouts reach through the whole block, so dirt can fall through it.

I made this for my knifes, so i can't guarantee that it will fit others as well, so i added a drawing of the allignment of the cutouts. The ellipses around the cutouts represent the knifes handles.
