Cutting board stand (Schneidbrett Ständer)

I ever had the problem, that my cutting board in the kitchen slide away. With this cutting board stand you can store up to eight cutting boards without risk to slide away.
Just print out all parts twice and click them together. That's it.

Parts to print:
2x Schneidbrettstaender.stl
2x Verbinder.stl

Dimension: 130x140x150mm

If you see opportunities for improvement, please let me know.
