Cut in 4 pieces to be joined together, fits on ender 3 sized bed. Print using supports, face will be 3mm polycarb you will have to cut to size, but can decide to not use it. You will need to install m3 threaded inserts in the polycarb mount, and install metal pins between the pieces, I used welding wire. For the clock face you will have to pause at layer for the numbers, or if you have multi colour capable printer that's even better!
