X's heat sink screw holes are non-standard width

I have a couple of the Pi X’s, and I was going to use some standoffs to stack them, but to my surprise, the screw holes are too narrow in the heat sink and in the short standoffs between the board and heatsink. The X itself is fine.

Maybe in the next batch of heat sinks, could you make those holes wide enough for a standard stand-off?

Thanks.

The holes on the big heatsink is standard M2.5.

Okay, I feel dumb. Thanks! :slight_smile:
