3D Model "Designer Cannon"

I create a series of prefabricated 3D printed constructors. The goal of the project is the development of 3D printing for educational purposes. The model is modeled in the Fusion 360 program.
The printing material is white PLA. The reason for choosing the material is simple:

- low shrinkage. And since the elements of the designer should fit together without fitting, shrinkage is the most important factor.
- Excellent adhesion. Since the gun itself is printed standing upright, a good adhesion of a small area is extremely important. However, you can still print only with the raft.
- Safe. The constructor should be safe, where without it.

The advantage of printed constructs is obvious.

- Low-cost price
- you can select the desired scale
- a fascinating process of printing and assembling the designer.

The cannon consists of eight parts. You can collect it both on glue and without it. To paint details (if there is a desire) it is desirable to still in the disassembled kind.
