3 identicle parts that slide together in a satisfying way to create a cube. Once assembled it needs to be held and moved in a specific direction to seperate. clearance between the parts is around .3mm allowing for smooth movement without binding. Since these parts have faces that slide on eachother printing in a higher resolution might be beneficial to the tactile feel. this design is intended to be printed without supports utilizing the bridge functions of your printer. i have left some extra tolerance at the bridge location to account for some sagging. Bridge length is 22mm. Cube size at default scale is 45mm.
