Mini Dupont crimper

thingiverse

This is for small DuPont connectors that fit inside RAMPS board plugs. The tolerances on these connectors are extremely tight! If you're having trouble printing one, don't worry – it's not supposed to be impossible. This design doesn't crush the connector firmly but helps fold the tiny tabs in the right direction, allowing a needle-nose plier to press them flat afterwards. You can also tap the crimper with a hammer after you've opened it by hand to close the jaws tightly. Feel free to modify this and make a stronger one if you prefer. Purchase uncrimped connectors and plugs at places like BangGood for about $7; you'll also find the real tool available there for $17. Print the design solid, then attempt making custom plugs with some patience and curses, using a magnifying glass for assistance!
