Molex MX150 Male Header Receptacle for Tesla Small Drive Unit

thingiverse

3D Printed Molex MX150 Male Header Receptacle for Tesla™ Small Drive Unit Inverter. The stock male header receptacle is very brittle and can be easily damaged. OEM replacements are not readily available, so I decided to make my own. For a weatherproof seal, run a bead of silicone along the integrated groove ring (see last pic). The brown connector in the pics was printed using ASA, and the black with ABS. The only supports needed are directly under the latch to ensure a nice square surface for the harness clip to latch onto. I recommend using a brim with ASA to help keep it affixed to the bed during the long print. The connector does not need to be clipped onto the logic board as the stock connector does, so the blue retaining clip is no longer needed. Position the connector in the inverter case and secure it with the two screws (marked green). Carefully reinstall the logic board so the pins go through the connector, and be sure to tighten all of the screws securing the logic board/tray to the case. You may want to leave the two green screws securing the connector a little loose at first so you can gently insert the harness just enough to align the connector with the pins. However, be sure to tighten up all of the screws before attempting to push the MX150 harness all the way on until it clicks.
