M2.5 bolt

[WegnerDan]

Is there a reason for using a M2.5 bolt instead of just using a M3 bolt for the knife holder?

I have plenty of M3 bolts in a lot of different length and head types but almost no M2.5 bolts. It seems with a little modification, M3 could also work.

edit:
I've modified the files a little and tried a M3x16 SHCS and it seems to work and seems to have enough play.
