Would love to see some of your prints on here! When I was younger my dad and I built a 3D printer, and I loved it. Since then I haven’t had the funds/time/space to get back into it but as that was like 12 years ago, I know 3D printing has gotten much higher tech.
Prusa Mk4s, but probably any modern printer could do it. It just has to be high enough quality so the small magnet balls can rotate so they can self-align and click together.
