This Assault Phaser model was almost perfect. I resin printed it and wanted to also have a P1. As well, the back fins were easier to install and glue in when I printed them both as one piece.

The P1 is remixed. I had to do a bunch to repair the original file, then it needed scaled 91% to fit the model. I joined the fins as mentioned and also hollowed out the "cobb" that goes under the forward slide. Again - this will work when resin printed - I don't know about FDM printing.

You'll also have to dremel out the rear support of the slide to get the P1 to fit. I plan on installing a magnet on the bottom of the P1 and the top of the grip frame. If someone wanted, I'm sure they could get the slide to slide back and forth on the frame as well. I just haven't gotten that far. I might requiring remixing the two grip halves with grooves.
