This is my version of well known 12 pieces wooden puzzle. It is designed to shine in some nice silk material but can be easily printed of any other. Attached are two versions of the puzzle that differ only in the shape of the small side edge, one has smooth surfaces and the other with a simple relief, the other dimensions are exactly the same. Fit of parts is relatively tight so all of them should be precisely aligned befero final locking moove, but it pays of in good structural strenght. Puzzle will not dissasemble by itsefelf that easy, once it is done. Size can be adjusted in slicer to your preferences. If you need help with solving, take a look for "12 pieces burr puzzle" on youtube. Hope you will enjoy and share some nice colourfull creations. :)
