10:1 Lego Blaster!
All 10:1 scale Lego mega-figs should be able to hold the blaster. Also compatible with the 10:1 Lego Battle Droid if you use the arms from the Mega Lego-like Skeleton. I added an optional print profile that includes the alternate battledroid/skeleton arms used in the above pictures (created by Julia Ebert). You can still use the original Battle Droid arms, the blaster will just be sideways.
Originally modeled by Arden Markin
I modified the original parts to work better with 10:1 scale Legos and fixed sharp overhangs for easier printing.
