I took the printing in progress coaster base and re modeled it so that it was a 45 record adapter.

This model prints in two parts so there aren't any supports required, the bottom part is the actual 45 record adapter and the top is the printing in progress coaster with 8mm nozzle.

There are two pegs on the base to properly align it to the top half so the two parts can be glued together.

The diameter of the printing in progress piece is the same as the original model so the E3D Revo remix should fit as well.
