Voronoi Style Desk Organizer, for pens, screwdrivers, anything really. With Upcycle insert

I need a desk organizer for my work table that could support a mix of everything, pens, small screwdrivers, measuring instruments, scissors, brushes you name it. 
I couldt find a good one so i made my own in a nice voronoi design as well.

Its might not look like it, but its designed to be printed without any support!
This is due to the rotations of the openings so they are all printable bridges. When i printed it i think one or two openings out of all of them had some slight curling of the filament but a little knife cleaned that right out no problem.

There are also 2 inserts available. The hole in the bottom supports a standard M3 bolt and the insert can also be extended using an empty toilette roll (EU) standard size and saves quite a bit of filament :). And i guess an even longer kitchen paper roll can also make it even higher in the center or cut to length you see fit.
