[POWER RANGERS] MMPR 1/1 blade blaster making

HI, guys



I am new here and I am a MMPR fan. I want a 1/1 blade blaster for my MMPR costume but just can't find one, the toy looks a little small. so I'm making a 1/1 blade blaster now. here are some pics of the 3d mold（gun style only). advice are welcome. I want to make it perfect as I can. I will use 3d paint to make it come out. lol. let me know what you guys think.
