After some successful tests of my QuadroCopter I decided to make a step forward. The goal is to make a smaller UAV which would be able to fly around a house. Carried by this vision I designed a CAD model of the mini QuadroCopter.

It consists of three parts:

• base plate (2 pieces),
• arm (4 pieces),
• landing gear (4 pieces).

Basically it is a smaller version of the previous UAV. The key differences are:

• PLA was used as the printing material,
• arms were designed for a certain type of motor mount which can be redesigned quickly if necessary,
• landing gear was shaped as a spring so it can absorb some force during landing.

Here is how the 3D model looks like:

Below you will find a series of photos which shows how printed parts look like and a pre-assembled UAV.
