Original TE Model was incomplete No Holes A Discord Group User RemDogKnap Remixed it added The Holes. Hols may print a little small so have some drills handy top open them up a little. theise connectors do work. I printed with both tree and full supports the full supports worked best tree not so well.

TE Connectivity 1-480305-0 3Pin Male Connector Corrected With Holes! AKA Molex 8981 The Original TE Public Model was incomplete No Pin Holes A Discord Group User RemDogKnap Remixed it added The Pin Holes. Make sure the ID is clean or the corners may crack. I made in PLA and PETG both fit great but I think Nylon would be better material.
