This is a small rubber band powered catapult based off of a paperboard model (see images). The 3D printable parts may have slight differences from the parts shown assembled, but fit together the same. NOTE: Be sure to print this model in extremely high resolution, as tolerances are drawn to the nearest 32nd of an inch. Glue and/or sandpaper may be required.

I'm a beginner in the 3D printing field, and hoping to buy an Ultimaker 2 in the near future. If you like any of my designs, you can donate Bitcoin to 1NYRBE4QK7e9tkN7LSEm8QURyyrC1BuqBg.
