Functional Artillery Canon Toy

This is a fun little artillery project that I have been working on.  You get to build a working canon, with functioning height adjustment. With shells that you load into the breech and then fire!  Good luck!

This is assembled using m3 screws, and m4 screws a couple of springs, and that's it.  I opted for the screws for the aesthetics and the ease of assembly.  I built this around using springs from maker world, specifically this one: 0.6x8x40 mm (5PCS) - BB017 however the performance if this spring leaves a bit to be desired. Instead I used one from a bulk spring kit I found at a hardware store.  It's most similar to a 1x10x35MM spring available on amazon.  The heavier the spring you can get to fit the better range you will get!
