Description

PDF

This is a way to test fit the C-40T gimbal without having the actual gimbal in hand.

I used a 5M 25mm hex socket cap for the yaw axis. Two 5M 12mm hex socket cap bolts were used for the roll and pitch axes. A 10mm bolt on the pitch axis would be a better fit but I don't have one on hand.

I printed these using PETG and a 0.6mm nozzle. I don't think it matters much which filament or which nozzle is used.

I included a model of the entire gimbal as a single part. This model differs from the model available from the manufacture. The original model included individual leads on several of the chips. I removed these leads and I also removed parts from the bottom of the PCB. In order to make the part easier to print, I increased the thickness of the PCB in order to remove the gap under the PCB.

The 1.7mm mounting holes have not printed well on any of my attempts. These holes are used to mount a camera to the gimbal.

Included a model (BarePlate) in order to cleanly print the mounting holes. The mounting holes are located on a 19.60mm by 21.77mm rectangle. These dimensions seem odd to me. I don't know if these dimensions are correct or not but they exact dimensions of the model I downloaded from gimbal manufacturer. It's possible (likely?) there is an error somewhere in the conversion from one CAD format to another. I'll update this description when I have a real gimbal in hand (one is on its way from China).

Model origin

The author remixed this model.

Differences of the remix compared to the original

Made model of entire gimbal easier to 3D print. I also separated each axis to individual parts. These individual parts allows testing the design in various positions. 

Added holes for 5M hardware.
