Meh, I don't know what the thing is called. We call it the "Big Ass Murder Machine," because we stick rulers in there and other random crap just to destroy. But when our superiors are around we call it the 3D drill .
That's a nice blaster! But yours is the ROTJ style, it's not too different, the scope is mounted differently and the barrel is different. The ROTJ has a cooler design, but I don't want to go too far outside of my costume style.
I hope my tutorial helps! Are you going to make the ROTJ or ESB style? This blaster progress should help you either way you choose.
Unfortunately the toy gun I bought came with a partner, I don't know what to do with the other. I have enough parts to make a second blaster, I might build one and sell the blaster cheap in the Cargo Hold. I'm not in this hobby to make money So you might see a "Buy it now" $30 blaster in the cargo hold in time.
With some creative trimming of an x-acto, here it is. I do need to re-add the bottom part which I cut off, the sight on the back, the depression in the part I cut out, and the little knob thing infront of the trigger. There are some parts that I need to fill in, some parts were too thin for the thickness I was aiming at. I also plan to fill in the barrel a little with the bondo. I don't want people do see a toy gun when they look down the barrel!
