Hello are there any assembly guide? I'm not sure how to mount my PCB to the case.. and how to mount the triangle feet
I don't have a Sprit case but I think it is just like most cases in that you put the screws through the screw holes in the PCB into the threads in the case. It may be a different kind of case in which in the PCB hangs and in that case(no pun intended) you need to attach the plate to the case. There should be screw holes in the plate and the case for you to attach it all together kind of like in an ergodox.
Here is a picture of a case in the first scenario:

See how it has threads for screws.
In this person's build of a Sprit kb he/she in fact screws the PCB into the case like I said. Keep in mind that there might be holes for screws on your PCB where there aren't threads for screws on your case and vice versa. Just put in screws where they line up.

Also pictures of the sprit case show threads for screws on the first page of this thread.

Just in case that is not how your case looks(I know there are a few versions of the sprit case), here is how you would do it the other way.
The plate might act as the top of the keyboard and then you would need to put screws through the holes on the plate and the rest of the layers of the case. For example you can see here how the screws go through the plate and all the way to the bottom of the case.
