How to design enclosure for two PCBs without any mounting holes?

I'm new to 3D design but I'm trying to learn Fusion 360 to design a case/box/enclosure for a few small electronic PCBs:

The problem is the left PCB has no mounting holes.  Can anybody give me any tips or samples of how to secure this without using glue?

 

The full enclosure will connect the left PCB to the right PCB so I need a case large enough for both components.

 

Thanks so much for any help!

I'd start by modeling both PCBs using a caliper to accurately measure dimensions.

Then we can start talking about how these are connected e.g. what pads on one PCB are connected to which pads on the other PCB.

Then we can see if we can orient the PCBs favorably and then we can design a housing around it.

My car key fob simply uses plastic pins molded into the case and some ribs to hold the board in place.

No fasteners.  

Edit: I missed circling one at the lower left at angled edge of board.
