All parts including the four guards fit in the Potensic Bag for easy
transport.
Here are the four propeller guards.
Each 3D printed guard has three small support tabs.
These secure the guards to the printer bed during printing.
Just cut them off.
Each guard has two very thin plastic shields
between the outer guard rails.
They can be left in place as shown here
or cut off with a knife to minimize weight.
Just snap the guards onto the drone as shown here.
This bottom view shows the guards in place.
The motor bottoms are open to air flow to keep the motors cool.
