Xicoy angle sensor mounts.

Hello all.
I have just finished designing a new accessory for the Xicoy CG machine. More specifically for the angle sensors.

I found out that the sensors were a good idea, but in practice were difficult to use because of the fact that it is offered as a bare IC board and that it is not flat due to the heat shrink protecting it for a portion of its length.

I tried using it with some sticky paste placed underneath the board but I could never get proper stability out of the sensor and was having the issue of the board moving with the flight control. I did not want to use tape to place it on the aircraft as it could damage some thin paint jobs.

So I decided to find a solution to give justice to this wonderful little accessory and be able to truly achieve its 1/10th degree precision.
I CAD designed some mount with the following requirements in mind:

A wide an stable base to anchor the sensor on the flight control surface.
Inner ribs offering a positive stop for the sensor IC board, thus a stable position of the electronics.
4 inner dots of 0.5 mm that would make me feel that the board is clipped in position.
A recess that would allow the positioning of 4 sticky paste balls to lock the sensor in position and prevent it from moving when the control is actuated.
Made from my favorite orange transparent resin and laser precision printed to 50 micron resolution.
The transparent resin would allow to see the status LED of the board.

Here is what I came up with:

And the mount after the printing process as seen from above:

And from the bottom:

With the board installed.

Note the recess left below the base:

That allows placing 4 balls of sticky paste.

Here is the sensor placed in position. Note the blue status LED on the right corner.

Let me know what you think about it.
This will be included in each Deluxe bundle from now on.
