This is a replica of a revolver. Not really sure what kind of revolver but, I got some of the dimensions from a page showing the specs for a Ruger SP101 (This was the first thing that popped up on a google search for "snub-nose revolver"). The cylinder spins but there are no other moving parts. This is my second design and if I tried to get carried away with over engineering it, I would have never finished it. First things first, the warnings, be responsible with this, it's obviously not a real gun, but I wouldn't recommend bringing it in public, you might get shot by someone who thinks it's real. Also, I know alot of you, like me, used to play with toy guns as kids. Times have changed, so don't give one of these to your kids. He will bring it to school and show it off to his friends and probably get in all kinds of trouble. Use your head. Print in fluorescent red ABS only! Print at YOUR OWN RISK, Neither the creator of this object nor www.thingiverse.com is responsible for anything that happens to you because you printed this object! Ok, sorry about all that, but it had to be written. Print one of each part, glue them together. Get a piece of filament and stick it through the cylinder and into the two holes on the body and the cylinder will revolve. If you are printing with a raft, make sure you make proper adjustments because the body and the grip are rather big and the raft may go over the edge.My printer isn't calibrated very well, so my print didn't go very well, I used a raft and some of my corners warped any way. I bet someone with a finely tuned machine could print a much nicer copy then mine.
