This bolt should be able to cram some lead and get a heavier bolt.. Seal back of bolt with J/b weld (which is recommended) or use melted pla There is a possibility of having too heavy of a bolt and cause cycling n feeding issues.. If so try lighting bolt spring tension.(Or drill into back with a bigger dia drill to lighten bolt.) PRINT ( orientation should be with bolt face faced to bed) Layer Height .16-.2 Walls 5-8 Infill 100% Support could be everywhere or bed only Adhesion none-brim or even raft if need be. Any questions feel free to ask..
