This clamp is for a StreamDeck (MK.2) to mount it to a 8040 alu-profile on your simrig.
Print this part with the big opening down on the printerbed. So you don't need any support and the clamping face will get a good fit.
There is only one side of the clamp as a stl-file. The other side you have to mirror this file in your slicer. You can print than both parts in onetime.
I use PLA with 30% infill and no support.
