This is an ISCG03 Bashguard I printed on my Elegoo Neptune 3 Pro with Black Petg Pro filament. It should work with 30 tooth chainrings and smaller but I’m not certain if a 32 tooth will work. It is incredibly strong and will handle some heavy hits! This does not include the right bolts but it works with M6 bolts and attaches to the ISCG03 mounts on your MTB. Any questions please let me know. Thanks!
