Modular Stackable A4 Paper Tray

This is a Model for a modular, stackable paper storage for your desk, it stores DIN-A4 papers.The models require no supports. I designed this in a way you can print the 3 single parts and the 4 long and 4 short pins. You will only need the short pins if you want to stack multiple on top, and you don't trust the small guide rail. After you printed the 3 parts and 4 long pints, you can stick the 3 parts in one another and put the long pins in the holes. Since I don't know the accuracy of your printer, you might have to in- or decrease the size of your pins. If you want to stack multiple of these on top of another, you can print the short pins as well and put the min the small holes. If you want to remove the large pins, I left a hole in the bottom of the parts, so you can push the large pins out. In case you need any other sizes, please let me know.
