This is a remix of the Colorfabb Cannon design by Labern, originally found on Youmagine.com. I'm posting a remixed version here because it is almost impossible to find any of the original free models on Youmagine now that they have changed their business model to a paid format. Labern has kindly given me permission to post this remix on MakerWorld.

Most of the parts press fit together. You might need a bit of glue for the bolts in the legs.

The plates are separated by material color and I used the following materials for the print in the photos:

• IIIDMAX PLA+ Coyote Brown (Frame and Wheels)
• Bambu Lab Tough PLA Gray (Bolts, Handles, Axle, Wheel Rims and other small parts)
• TH3D PLA Copper (Barrel)

I made a few minor modifications to Labern's model based on my build experience:

• Scaled Bolt diameters (Long and Short) to 95% to eliminate need to drill out holes to fit.
• Scaled pin diameters on Handle to 95% for fit.
• Revised Wheel Rim to be an actual rim and set it up as a 2-color print with the Wheel. (The original rim was meant to be printed in vase mode as a separate part.)
