Gridfinity tissue holder

Tissue Organiser for Gridfinity. It fits the standard tissues that are common in Germany, which are called Taschentücher. I don't know if this tissue format is used throughout Europe or even internationally.

The dimensions of a single tissue should not exceed 107 mm x 54 mm, which is the area of the baseplate. 

All in all, it holds about 27 tissues. As you can see, it has a compartment for spare tissues.

I included the step file.
