Pazu's gun/ grenade launcher

thingiverse

This is Pazu's gun form Castle in the sky. I scaled mine up to 1000% and that felt a little too big (I wanted it big to make me look more like a 13 year old Pazu carrying an adult's gun but it was even too big for that). To over size it for a cartoony look 800% or 900% might be alright, and to have it look like you're an adult 500% or 600% might be what you're looking for. Print the handle first if you're unsure as that will give you the best feel for what size you want based off of how the grip fits or doesn't fit in your hand.
