Reply to Arcade button mod gone very wrong....

Shit guys.

I need help.

I took my plate to the machine shop and they said the CAD files were useless to them.

I suggested they use the overlay as a guide and now the holde they have drilled are slightly too big for the buttons.

The buttons fit into and lock in, but they move around and are not steady.

Does anyone have any ideas of what I can do to shrink the holes by a mm or 2?

I've got a festival that I'm doing in the next 2 days.

Shhhhhheeeeeeeeeetttttt!
