Pretty cool thing.
I had to flip the VCC and Data pins before it would work on my controller.
The controller is one of the generic USB controllers on eBay, Amazon, Banggood, Aliexpress, etc etc.
I printed it with custom supports using Simplify3D.
Thanks for posting it!

I use 210 hotend temp and 60 bed temp.
60 is new for me, before this, I used 48 as bed temp. 60 seems a bit hot...
