I received some Leman Russes from a friend that had the sponsons weapons glued in. Due to wanting changeable weapons I designed this.
This is designed to print flat on its back. to minimise wasted material. I still used supports for the cylinder top and bottom.
I printed this on the Ender 3. 0.2mm layer height with supports turned on (just in case the little cylinders at the top and bottom didn't print right)
