I designed a stand for my Fiio M11 that had a number of features:
I wanted a charging dock style stand that would keep my M11 charged up without having to fiddle around with plugging and unplugging a charge cord.
Needed the ability to set my M11 on the stand without unplugging the headphone/IEM cord.
Wanted something that was easy to use: a stand I could just drop the player on without worrying about aligning it with the stand, or the player falling off.
It had to look decent. Maybe not like modern art, but something that would blend into the decor on my desk.
No supports. Just print on it's side and no supports are required.
I designed the stand to be dual purpose. To make it a charging stand, I ordered a 90 degree USB-C adapter from Amazon. Specifically this one: https://www.amazon.com/gp/product/B077XCWJTG/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 It fits in the square holes in the shelf that holds the Fiio, and the underneath the shelf in the backrest.
I also made it so it could be used without the USB adapter. Just run the cord through the lower hole and plug it into the Fiio like normal.
