Sometimes cast lead buckshot doesn't come out perfect.  At trick to get them more uniform is to tumble them in a rock tumbler.  However I didn't want to pay for somethin I'll only use once or twice a year. I also didn't want to coat my tumbler with lead dust. Soo I designed this insert. For me I found tumbling for about 6 hours works the best.

I printed using Bambu P1S. printed with 50% infil on the insert and 15% on the lid using Gyroid infil.
