Picture of Cannon Planters
IMG_2395.png

I'm a huge fan of 3D printed planters. They are great at holding many different varieties of succulents, micro-greens, etc and they look aesthetically pleasing, especially compared to more utilitarian pots and vases.

Recently, I had a great idea. If I 3D printed a desktop cannon, I could put plants inside the barrel, which would plume upward like the smoke after a cannon is fired.

I decided to create 2 different types of cannons to wage war against each other on my desk. The first is the mortar from Clash Royale, a mobile game by Supercell. The second is a bomb tower from Bloons Tower Defense 6, a mobile game by Ninja Kiwi.

Softwares needed for creating these models:

1. TinkerCAD - TinkerCAD is an easy-to-learn, online CAD software that you can find here.

2. Cura - I use this software to slice my files for printing. I used the Dremel Digilab version of Cura so it would be compatible with my printer. There are other slicers out there, also, such as Simplify3D, but Cura is currently the best free slicer.

Tools needed for printing these models:

1. 3D Printer - I used a FDM 3D printer to make these models real. I own the Dremel Idea Builder, which can be found here. However, any FDM printer capable of printing at a reasonably high quality should be able to create these models.

2. Filament - 3D printers place melted plastic in layers in order to create 3D objects. This plastic comes in spools called filament. I used Dremel brand PLA for these 3D prints; however, any filament will work.

3. Post-Processing Tools - After you have printed your models, you will need to remove all of the supports from the prints. For this, I used a small screwdriver, pliers, and tweezers. You can optionally also stain this model if you purchase wood filament.

No problem, I'm just hoping more and more people will get interested in 3D modelling and 3D printing from my Instructables.
very nice!
