Print the following pieces. You will want to print at fairly high resolution (at least .2mm) because of the steep angle, otherwise it could be droopy.... 1x tower.stl 2x tray.stl 4x pin.stl Snap the pins into the holes on the tray, facing inwards, and then snap the tray to the tower. Repeat on the opposite side, and you're ready to play! EDIT: It looks like some people are having trouble with the pins. I print the pins in ABS and they work well, but it's quite possible the pins don't print well in PLA.
