2 types of stands for the 8bitdo Ultimate C Contollers:

Original: Same shape as the charger stands that come with the more expensive models

Large Base: Flatter front bottom. I made this change so to print it easier and I think it looks pretty nice. You can try adding any SVG symbols or text you like (as I did with the Hylian Crest on one of the models in my pictures). The larger model's front is flatter so it looks better on them.

They may fit the other 8bitdo Ultimate controllers, but I can't be sure as I don't have them. But they seem too similar not to fit.

I was struggling to find good models a while ago so I purchased a raw scan and smoothed/changed it.
