About this 3D model

This model has been updated, there is now a supportless version avaliable here: mmf.io/o/204570 This is deceivingly hard 8 piece durable puzzle box designed to be difficult to solve and simple to print. Any rigid material should work. However 2, 5mmX1mm circular MAGNETS ARE NEEDED I used these magnets: shorturl.at/lvxEP ASSEMBLY AND SOLUTION PDF'S IN THE DOWNLOAD ---------------------------------------------------------------- This is my first design and I would love some advice if anyone has any. Thanks!
