You have access to a FabLab? The 32 solutions shared under CC-BY-NC-SA license will allow you to cut your own puzzles and tray. You don't have access to a FabLab? Snijlab will cut the pieces and send them to you. Our advice: use 5mm transparent plexiglass acrylic (PMMA). You want to delegate us the work of ordering and assembling the puzzles? Go to Artelude to buy our ready-to-use puzzles. We also propose 8 compositions of 4 puzzles. Each composition allows you to build either a cube or a large square. We use those stackable boxes for storage. Lost a piece? Contact us at info@qucub.com.

Note : This page corrects and completes the "Square Trisection" publication of Christian Blanvillain and Janos Pach (2010).
