Charlie , Yes i make dice towers, they are made of aluminium, with 4 ramps to tumble the dice,the ramps and tray are covered with rubber to deaden the noise and the base is covered in a type of foam. they are designed to take the mmp dice others can be used tho like the schwerepunkt ones available through Andy Ashton at Second Chance Games.
