Jamma finger board project boxes

I’ve seen some people use plastic boxes with a slot cut out to hold their jamma fingerboards for stuff like hooking up 360’s or other jamma adapter systems to arcade cabs. Just wondering what other people out there have used for this and where a good place to get some would be.

(and before anyone directs me to arcadeotaku- I’ve posted there too. it’s just a much slower forum than srk :stuck_out_tongue: )
