Since I swapped out the springs for using 10x20mm rigid aluminum spacers instead and insulated the beplate as well, I needed a harness for the bed wiring that would fit.
Printed from PETG (with a 0.6mm nozzle), no supports needed.
The author remixed this model.
Remixed version of the “Neptune 3 Pro Bed Harness off center.stl” to fit 10x20mm rigid spacers (bore: 10.5mm ID).
