As part of my final exam for one of my first Mechanical Engineering classes, I had to redesign something. I more or less made an airsoft 40mm Grenade Pistol. This was a group project, but I ended up doing about 90% of the work.
Program is Solidworks, in case you were wondering. Wonderful program, it's a joy to work with.
Comments, questions, concerns? Anyone want the model, or have suggestions for making it better?
