This is my take on a charging stand for the elite series 2 controller. It holds the charging dock along with the 4 attachable thumb sticks, the other dpad, and the tension adjuster tool.  The top left thumb stick slot is deeper to accommodate the extra long one.  

I made it with slots to optionally add ½ oz tire weights to help the stand stay in place. I used these weights

There is a hole for a 10x2mm magnet in under the dpad slot.  I find this helps it hold the round dpad better but it works fine without it. 

The base portion is meant to be printed in TPU for extra grip and is also optional.
