VW Seat Adjuster Knob

prusaprinters

These knobs are either perpetually out of stock or are garbage reproductions that look like someone described a knob over the phone to the overseas company making them.  I had access to a couple original knobs for modeling.  Even they were a tiny bit different from each other so I split the difference for my model.I printed in ivory PLA+ using 0.1 layer height with a brim for stability.  While it was probably not necessary I liked how 60% infill gave the printed knob a similar heft to an original knob.The 0.1 layer height made it easier to sand/polish out the layer lines.  I'm not worried about interior heat as this is a weekend car and won't spend much time in the sun closed up.After printing, lightly sand with 800 and then 2000 grit sand paper.  Mounting it in a drill makes it a little easier.  I found Mother's Mag Polish did a good job giving it the final shine.  The result is almost perfect and at least as good as the best reproduction.
