Confirmed working, Thank you

I suspect it's either coming from

MountingHole:MountingHole_2.5mm

or

Connector_Dsub:DSUB-15_Female_Horizontal_P2.77x2.84mm_EdgePinOffset4.94mm_Housed_MountingHolesOffset7.48mm

Though the latter should NOT produce a mechanical tie point to the case. it's a snap in solder connection for the DSUB .

Upgrade to 1.4.1:
