Based on all of my testing with different prepresses You will want to run a 2x4 (puck size 1.5x3.5) press that will hold ~4g to ~5g. With those plates and pressure. Here is what you would order to make your own.
Remember when you squish the puck it grows in diameter considerably and you do not want it squishing out past the edges of the plates.

Here is the closest thing I can find
premade ($70. on Amazon) the problem is that with only 1" tall it will be hard to get 4 or 5 grams in it. Maybe make two pucks and stack them to press?
