This is a pretty basic paper organizer, with supply holders for your pens, pencils, or anything else on the sides. If you just print out organizer.stl, you will just get the paper organizer. Print out holders.stl to get the easily attachable supply holders that just snap into the sides of the paper organizer. All in all, the full print will take about 400 grams of filament. This is about $7 of filament, which is much cheaper than the ~$15-20 this product might normally cost.
