One of the overlooked, but vital pieces to complete that clean fight stick mod are these little plastic pcb feet that are self adhesive (and strong thanks to the 3M technology). There are a variety of situations where there's really no practical or clean place to hold down the PCB (i.e. PS360+, Brook Universal Fighting Board) with traditional screws or spots where it just looks cluttered to do so.  

With these adhesive pcb feet, you can pretty much mount this anywhere as you choose and not damage the case by drilling unwanted holes.

You're purchasing a set of 4 of these and fit the hole size for Akishop's PS360+ and Brook's Universal Fighting Boards.  

True 3M technology.  There are knock off adhesive types out there that cost less, but we opted for the superior quality as we're talking about the importance of how your fight stick holds up for the long term.  You definitely don't want your PCB shaking loose inside due to a few cents you may have saved.
