Description

This is a keychain cannon, ready to defend both the office and your home. It has a spring to shoot cannon balls. 

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

New: 
Now 1200 first names are included as 3mf, so you can print your personalized cannon. Let me know if names are missing.

New: 
The cannon plunger holds one cannon ball securely in place, even if you put it on your keychain: In the bottom of the ball is a small identation, and on the holder you find a matching pin. Make sure the pin latches onto the holder when you load the ball.

New: Also the spring is updated now. It is based on the great idea of FailOften, to exchange the “round cross-section spring” into a “rectangular cross-section spring” to get better results with the overhangs. It really works! (I will update the other cannons as well) 

The model has a spring inside. The cross-section shows this and the pin holding the ball:

Printing

  • Print it without supports and as oriented in the STL. 
  • The cannon is fully print-in-place: No assembly required, just remove the cannon from the print bed and fire away! 
  • 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. 

Versions

You get 1200 names and the word pairs:

  • Pirate - Cannon
  • Arrr! - Booty
  • Plank - Dive!
  • Hands - Up!
  • Papas - Tool
  • Guard - Desk!
  • .. and a version without text, it was requested by wyldkit 

Let me know if you need other texts on the cannon
