ASSEMBLY REQUIRED
I've made a prop from the film Elysium. I used the concept art from the film to make this prop grenade. Assembly should be simple, there are locator areas on the parts that need to go together. Some things may need to have added clearance after being printed, the usual. But this should be a good baseline. Once completed you should be able to insert a spring below the safety grip and put in the pin. Basically if you pull the pin and let go of the handle it should spring up just like a real grenade.
I did not include the ring as I figured people would probably use a key ring or something. Also the pin might be difficult to print properly. If this is the case I will update or add one to print easier.
Overall height is 118mm and the grenade diameter is 55mm
Added a hollow version of the body to keep costs down, but I'm not sure how it will print!
