I just ordered and 3D Printer and scanner. any one know of simple objects I should try to replicate and print off (I was thinking mabey a knife of some sort) i have a CAD program on my Computer Im working on replica parts for 1894 lever action guns that i can use to make sure the part fits before I run a metal part on my CNC mill. and eventually work out a design for a double set trigger. the main thing is I want to make sure the 3d printer has enough accuracy to make those parts.
