This will ensure that you will not accidentally knock your gain while recording! this remix uses 4 M3-30 bolts to act as a barrier. In Cura, you need to use support on the bottom of the print but I opted to clear the supports from the holes up on top. the M3-30s will go in either side and bump into each other in the middle. You may need a tool to flip the -20 switches if you ever need to flip them.

switched the guards from thin plastic to M3-30 bolts
