The little rubber dots on the door step were cracking on my 1998 SLK230 and falling away, so I 3D printed some replacements.

Image #1 is the design file I created using FreeCAD 0.16

Pictures #1 & #2 are the "before" pictures of the driver (left) and passenger (right) side step panels, respectively.

Pictures #3 & #4 are the "after" pictures of left & right sides again.

I used Inland TPE filament (black) and a Prusa I3 Mark 2S 3D printer. Print time was just under 5 hours. TPE (thermoplastic elastomer) prints very slowly, compared to other, rigid materials.

So... what are those things called, anyway?

Thanks,

Dale
