Working Cannon

I upload new designs now mostly on Makerworld or printables.
If you want to support me, please download and like(!) this design also on Makerworld or printables. If the design gets enough downloads&likes, i might get a spool of filament for free :-).
All my latest creations will be available there, as Thingiverse downloads are a bit broken at the moment and also the customizers seems to not work anymore.
For latest Version "VL", please go to Makerworld!

Description

This is a working cannon. It has a spring to shoot cannon balls. Use the hinge to aim precisely. Print as many cannon balls (included) as you need or shoot paper balls, peas, etc.

In the base carriage, there are identations to store 2 cannon balls. (Better print two)

Use it as a permanent display on your desk, ready to fidget or defend yourself whenever needed.

Printing

Print it without supports! Print it as-is, the cannon and front of the carriage should point down towards the print bed.

• There is a print-in-place hinge included to aim precisely.
• The spring (inside the cannon) is 3D printed, and works well also if you print in PLA.
• The design is fully print-in-place. No assembly required. Just remove from the print bed and fire away! The hinge and piston might need some initial movement to get going.

Models included

• You can select a strong or weak spring (weak one for kids, to make it easier to pull and reduce potential injury)
• 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
