Nerf SlingFire replacement lever

Couldn't find this model anywhere, so I took josh's (Eletric Squid) model and just made it not big. The proportions are still a bit different from the original lever, but it should be a bit more confortable for people with larger hands.

I recommend printing with all walls or with infill set to 100%. Maybe inserting a metal rod in the weak section, so it lasts longer.
