Tool to create hyperlapses with DJI controllers (Rocker Speed Controller)

I have a DJI mini 3 and I was looking for a tool to help the drone to make smoother and consistent movements, inspired in this video: https://www.youtube.com/watch?v=xMErYnmOejY
If you search for "Rocker Speed Controller" at marketplaces, you'll find an off-the-shelf solution for around $6.
So I found the solution here: https://www.thingiverse.com/thing:5277645
But the original solution don't stay tight at the stick, so I made this modification to solve the problem.

Tip: Fixed the bolt and the nut (M4) with instant glue.
