I found the foam gun I want to use for one of the shoulder mounted weapons. Yes, my garage door sometimes doubles as a paint test area.

It's a Dart Zone Enforcer. The 40 dart capacity, full auto firing, and slow rate of fire all appeal to me. I should be able to wire it up for remote firing and since it's slow I won't expend all 40 darts in 2 seconds.

I have a "spare" R2 dome that I used to get the neck bearing centered. I need to lower it about 2mm so I'll have to print up spacers. I also permanently affixed the legs.

Some droids are capable of 2-3-2 which means they will pivot up to two legs and pull up the center leg. Then they will reverse this process. It's a lot of work and looks amazing. Unfortunately I don't have the room inside BT for all that so I'm permanently putting him into three leg mode.
