DB19 3D printed Male & Female version
From Amazon you can purcase these pins. I know the male pins work but I have not tested the female pins in the female 3D printed connector. https://www.amazon.com/dp/B09BZ789HJ?psc=1&ref=ppx_yo2ov_dt_b_product_details
Recently purchased 400 pins from this link in the US and they work great. https://www.powell.com/item/Tri-Star-Electronics/M39029-64-369-Circular-MIL-Spec-Contacts-20-AWG-PIN-CONTACT-MIL-DTL-38999-SERIES-561301
Another source for the male only pins this unit was specifically designed to use is: https://www.distrelec.biz/en/crimp-contact-pin-pu-pack-of-100-pieces-deltron-connectors-px1-awg-20-24-crimp-set-of-100pcs/p/14416914 This is from Europe and I can't seem to order from the site and have them shipped to Florida. Joakim orders them and sends to me.
The best I have found is to order these items with the choices of: 3D Technology - SLA resign, material - black resin, color - grayish black, sanding - yes from JLCPCB and they are about $1.00 each for the male version.
USE THE FEMALE VERSION AT YOUR OWN RISK AS THIS IS WORK IN PROGRESS
