About this 3D model

I created this project because I was bored in class. Me and a friend both like to play chess. I designed it so it it small and easy to travel. I have calculated tolerances on everything so normally you can just print this. For the hinge I used 2xM2 nut and bolt and 2 spacers. for the lock I used an M4 bolt. I hope you'll have as much fun with it as me and my friend. If there are any problemes just let me know. When it's completly assembeld, it's 100x110x44 mm.
