Just a little 3D Tic Tac Toe board i decide to make.
The columns could be a little hard to work with, but with good enough adhesion, it should work fine. Do not try to scale it down, or else the columns won't print, unless you have a super thin nozzle (they are .4 mm wide)
Simply take the small columns and insert them into the holes on the top and bottom of the 3 boards, stacking them to form a tower. The small peg on the side is for putting the game away. stack the holes o the side of the boards onto the peg and store in a small box/drawer.
