This is a printable breech riser for the Crosman steel breech.
The included STL is a 5mm riser.
You can customize the riser height in the SCAD. You can also tweak the hole diameters also.
Keep in mind you will need a longer hammer pin for cocking, and longer screws: the rear is an 8-32, and the tiny one in the loading port is a 4-48.
