DC-15 / DC-15A (there is a bit of confusion in naming) blaster rifle used by clonetroopers in Star Wars II & III.
This is a realistic version (not the Clone Wars stylized one) and I dare to say it's the best free one, at least I couldn't find more screen accurate model.
You will need to split model into parts, if you want already split model, it is available at CGTrader: https://www.cgtrader.com/3d-print-models/art/scans-replicas/dc-15a-clonetrooper-blaster-rifle-star-wars
Length: 130 cm (51")
Update [31-5-2019]: I'm currently working on completely remodeled version with all the details (like knurling on grip etc...) that are present only in textures from Battlefront II but not in model itself. I'm already half way through.
Update [27-7-2019]: Finished the remodeled version. It is now accurate to the game textures.
