The STL is high-resolution / huge.

You may want or need to re-save the STL in OpenScad at a more-coarse resolution.

Just change the "$fs=0.25;" line to a larger (more coarse) number and then re "F6" and re-save STL.

I had heard of dipping parts in acetone to smooth them. I gave that a shot. Pretty amazing, pic attached.

Beware of the acetone. Some seeped in and the knob melted a bit from the inside. I think it needs a tighter fill and less time in the acetone. I'll try some other recipes.

Thanks for the pic with dip, though. Inspiring. You could try baking out the acetone after the dip: It's very volatile...

First time I see a printed object smoothed with acetone and I'm pretty amazed.

Beautiful quality ! :)
