Not only do I also own a PRM-85 but I do have part-time access to a 3D printer. If I can get the prototyped models (and the model itself fits within the limits of the printer bed)I can verify that they fit together in an HP 80 series machine (85 in my case)and that the board itself fits inside the enclosure however due to membership restrictions at our local makerspace I cannot use the printer to fulfill any orders, plus they will eat up a lot of filament. -John
