Order is half the battle they say.

I have designed a fully printable desk organizer without supports, available in three different sizes and with 16 compartments each. 

With and without overhangs, but both can be done WITHOUT SUPPORTS.

The organizer can also be stacked on top of and next to each other.

I have created different profiles, for each size one with overhangs and one without, please do not change the object settings, I have experimented a lot and these are probably the best. There is enough tolerance, if you like it a little firmer then leave a little of the brim.

It looks better visually with the overhangs and you do NOT need any supports if you print the overhangs very slowly, but my recommendation is to print them without overhangs.

Using a brim is highly recommended!!

Hope you like it!
