Anyone with any revolver and a printer and some experience modifying files could probably get this done. Print an oversized ar style grip modified to open like a clamshell, hollow in the middle with enough space to fit the revolver grip, closes with 4 countersunk machine screws. Pack the extra space with rubber putty(or silicone molding putty for a more permanent fit), and then sandwich the revolver grip inside. Close it up and you've got a generic print that will fit almost any revolver while also absorbing some of the recoil if you use a rubber or silicone putty for fitting.
