I made a version of this dock for the AirPods Pro. You can find it here: https://www.thingiverse.com/thing:3961573
2x M3x8 screws or shorter needed
I found this AirPods Charing Dock on MyMiniFactory, which design I really liked: https://www.myminifactory.com/object/3d-print-airpods-dock-101551
The problem with this model was though that it was pretty hard to get the cable to fit. Also it seams that the connector was not correctly centered, so the AirPods were docked slightly tiled.
I then search for another model on Thingiverse I found one (1985306) which I really liked due to its simplicity. But I wanted that design combined with the multi color capability of the other model on MyMiniFactory. So I designed my own one in Fusion360 (F3D and STEP files included).
I also changed the way the parts are put together so you see as few seams as possible. You can see how you can put together the peaces in the images I have provided.
In the last step two M3x8 screws are needed to hold the dock together.
