Supports for the original filter board on Primal Rage arcade boards when fit in the awesome Primal Rage Plexi case by plasticfactory (link below).  The plexi supports the JNX Rage filter board pcb, but it doesn't natively support the original filter board. This model provides left and right supports that connect to the JNX Rage standoffs on the plexi.

Attach the supports with the M3 screws/washers provided with the plexi kit, and attach the other side to the filter board using M3 screws and nuts (I used 12mm but 10mm would also likely work).

No special print settings required, I printed in PLA+ with default settings with no issues.
