Some of the biggest pain points for CPS3 owners is the PCB flexing where you install the cart. Over time, the customs around the pcb eventually require reflowing causing a number of issues on the board. Thanks to clintkolodziej on Arcade Projects for designing these CPS3 pcb supports to alleviate that paint point.
Got them printed and sent to me. I’m not no longer praying each time I insert a cart and turn the cab on 
I can also confirm, these fit hursit’s case.

Without supports
With the supports. As you can see it barely moves now.
Once again, thank you for doing this design
