Bolt and nut for repairing an Acerbis Koerta body armor/protector jacket

My Acerbis Koerta motorcycle body armor was missing a few pins. I used NUT JOB | Nut, Bolt, Washer and Threaded Rod Factory and a caliper and designed a replacement. Printed in PETG, then I used some heat to melt the top of the bolt to the nut so that it will not come loose. A 1 mm washer is also provided, but it can be printed also thinner by scaling the z if required. Works great for me and might be useful for others too.
