First try at printing a ship's cannon. Came out pretty good. I can adjust the scale easily. The barrel on this one is about 3" long.I have decided to employ 3D printing on occasion when at scale, I want to achieve the detail I could otherwise not attain. At 77 years, I cannot accurately carve tiny pieces from wood. I can use a lathe and mill too but these are just additional tools, like the 3D printer used to mill pieces for use on ships. My Christmas present, with my better half's agreement, was to get a 3D printer and proceed. ( She does want me to print small, unique flower pots for her ever-growing succulent collection). It'll be interesting and fun. I want my models to be inspiring and fun to look at. There will be a learning curve because 3D printing comes with a lot of variables to overcome and understand. But I do need something to keep me busy!
