are there instructions available to assemble the dice tower.

Looks amazing. Good detail. Solid model. Totally unusable. To get the gap open enough to drop the dice, you have to push it down, which jams the whole thing up and breaks the pin to raise and lower the door. If used with just the handles, the opening is 1.25 cm, which is too small for anything more than mini travel dice. When forced open, it has a 2cm opening. Needs a redesign on that trap door mechanism. Without the trap door it does okay, but the drawbridge won't be attached. It is an all or nothing design.
