Wanting a more robust drainage system in my Langmuir XR plasma cutter water table I made a swaging die for a 3.5" kitchen sink basket.

I wanted some nice big drains that sat well below flush. I installed X4 in my XR and i am sure the die could do many more. The metal thickness is about 20ga mild steel.

The dies were designed in Fusion, exported as a step file to Bambu Studio and Printed with 100% infill ABS on a X1C. The backing plates for also design in Fusion and cut on the XR from 1/4 mild steel.

Here is a link to the Langmuir XR for those who don't know about their Plasma tables.
