Compact Mac Analog board shield snaps

For most Video Analog board shields you will need 5 snaps - easy to lose or break, and sometimes difficult to remove.   I printed in PETG .2mm layer with a 6 layer skirt, .3 mm away from the objets - on an FLSUN V400, and no, not anywhere near 600mm/sec.   PLA might work, I'm not sure how hot it gets under the cover of the old compact Macs?
