Sticky Note Organiser

I had a mess on my desk with sticky notes and pens laying around. So I designed this sticky note and pen organiser to take care of that.Sticky notes are staggered horizontally and each compartment is at a different height than the previous one. This allows for easier handling of the sticky notes. The front has a shorter compartment for smaller notes. The side has a compartment for used notes, that you don't quite want to throw away just yet... And of course a pen holder at the back, that I managed to fit a maximum of 18 generic pens into.Yeah it could be nicer looking with rounded edges, maybe it could be optimised to use less material. BUT I printed it once, it worked and I am not wasting anymore plastic on this. So feel free to remix, if you think it's good.
