This is a model of a piston trophy. Its broken into 4 components. A base, 2 identical bolts, a rod, and the piston. I have also included a bonus file so you can choose to print the piston as a solid or as a cup. Printing on an FDM printer will require the ability to plate the components or additional time to print each individually. The piston can be printed with supports in either direction but I recommend printing it top down for best finished results.
