This design is an stl file of a motor mount destined to be 3d printed in ABS or PLA to assemble your own drone or gimbal, the stl format allows you to immediately send the design to your favorite 3d slicer program and then to your 3d printer. The motor mount can accommodate motor with mounting holes ranging from 19mm to 25mm (which corresponds with most 35 size brushless motors and a lot of brushless gimbal motors). These motor mounts are made to be fixed on a aluminium or carbon fiber tube 14mm in diameter. The advantage of this design is that you can put the motor cables through the tube which makes it more clean looking. There are several different designs from which you can choose according to your needs ( coaxial motor mounts for 35size brushless motors for instance ).
The motor mount should be secured with 30mm M3 screws, washers on either side and a M3 lock nut. It is highly recommended to use 2 O-rings (size 9 (10.5mm x 15.9mm) or size 10 (12.1mm x 17.5mm)) to better secure the motor mount to the 14mm tube.
The recommended infill to print this object is between 60% and 80%.
