Not only am I a middle child, and my parents called me by my middle name, but the name itself is Odd with a T in front of it. I'm a life long tinkerer with a passion for hands-on learning. My grandfather instilled in me the "fix it rather than replace it" mentality. Now I'm learning to incorporate a 3D printer into my life. One major thing I want to do is to make molds of the 3D prints and pour aluminum and brass versions of them. Any tips or suggestions in that regard would be most welcome. I have a propane foundry now and will be building a larger one soon. My 3D printer is the Elagoo Mars base model. I'm just getting started! Help! Still learning Tinkercad!
