Beer Gun Opener

If you happen to print this, please add a photo as a "make" :) The original gun has a very nice shape but I found 2 major problems : - It was too big to print in my 20 x 20cm 3D printer - the trigger didn't work well I added the following modifications and it works very well - check the video ;) - reduced the length so it can be printed in a 20x20 printer - added 2 magnets to hold the bottle cap until you shoot ! - improved the trigger and added a second "spring" part so I guess it will last longer - improved the sight part so it glides fine and reduced the length so the elastic is more tight - made a hole at the end of the cannon so you may adjust the elastic frome outside - increased the diameter of the cannon's end screw hole to fit a M3 and a bolt - modified a part of the handle that hurted the hand - removed the side writting because it didn't print well with my printer - removed a little part in the cannon that was sometimes blocking the bootle cap when shooting Material : One rubber elastic band 2 neodymium magnet 2mm X 12mm 7 M3 X 15 I used something like a M6 x 15 to hold the trigger but I guess you can just print a cylinder. Please Remix ! One coin: round 20mm and 2 mm thick. Such as a 10 euro cent or a 1 dollar cent.
