Mario Coin Cube

Consists of a main cube and coin that inserts into a slot on top of the cube

the coin has space for an led strip to be stuck inside and wired into the base

the base is screwed to the main cube using 4 x 16mm screws (3.5 or 4mm width) and has a cylinder inside that an led strip can be stuck to in order to give nice even light output

the rear of the coin can be covered by the round plate that hides the lights and wiring and is just glued in place

I used these led strips which can be cut and joined however you could use a USB version if you wished
