Summary

I needed pushrod for one of the 3458A's I'm resurrecting from parts. I modeled this one without the button. I printed it in PETG on the Bambu X1 and it worked as designed. I used tree supports for the small Z at the sw end. Printed solid with 4 skin layers. I popped a button off of another old piece of HP gear and glued it the front of the pushrod using SciGrip 16 from IPS (Weldon)
