Designing holes for M3 threaded inserts in an ABS enclosure

0
A
1

Hi! In my design for a small ABS enclosure for an onboard sensor module I want to switch from molded bosses to heat-set M3 inserts for the lid screws. Before I finalize CAD, what pilot hole diameter and wall/boss thickness should I design so M3 inserts install reliably without cracking or deforming the part? Thanks!
