Description

This is a tiny keychain cannon, ready to help you both in the office and at home. It has a spring to shoot cannon balls. Use the hinge to aim precisely.

The cannon base holds one cannon ball securely in place, even if you toss it around with your keys. This way you have always ammunition availabel on the go.

Print it as a toy for your kids, grandkids, or present it to friends as a gift.

Printing

  • I spent quite some time to optimize this tiny version of the normal sized cannon. The tiny version prints well, but in case you have issues, i recommend to print the normal version to make sure that your printer is dialled in well.
  • Print it without supports and as oriented in the STL. (The cannon and front of the carriage should point down towards the print bed.)
  • The cannon is fully print-in-place: No assembly required, just remove the cannon from the print bed and fire away! (The hinge and piston might need some initial movement to get going.)
  • The cannon is designed for easy printing, so bed adhesion should not be an issue.
  • The spring (inside the cannon) is 3D printed, and works well also if you print in PLA. There is a hinge included for aiming. It might need some initial movement to get going.

Models included

  • There are three models:
    • The cannon only, you can also print this as initial test for your calibration.
    • The cannon without wheels
    • Then cannon with wheels. The wheels dont turn, but look cool. They also print without support material
  • There is also a cannon ball included
  • Update 15.9.:There is also a version with a bigger wiggle in the hinge available (standard: .25mm, if_hing_ist_stuck_use_this: .35mm)
