My first 3D printed part from the new 3D printer. It is printed in ABS plastic and contains one magnet and one dummy washer to give one pulse per rev of the driveshaft.

Since the trans is converted to drive a mechanical speedo, a speed signal for the ECU
was needed. The stock VSS sent a signal to the Astro gaugecluster where it was converted in to 2000 pulse per mile.

This collar contains one magnet that gives the ECU approx 2700 ppm which is close enough to get the converter lockup to work ok, and to enable highway mode for the ECU.

Nice job! Does the part work as designed? It's cool to see a useful part made with the 3D printer to solve a problem. Thanks for the update!
