Fwd: Re: rounding bottom edge

My take on a top and bottom fillet for a 3d shape.*
There was a slight error, that may or may not have been corrected.
No need for BOSL2, just basic scad code.

How do I add a .5 radius rounded bottom?

That fillet library works by making a stairstep "curve" using
projection(). So it's quite slow. And the results look terrible.

There is the result applied to a short text. It took 8s to preview with
four layers. I guess maybe it's OK if you match the fillet steps to your
printing layer height? But if you want a 3mm rounding that means 20
layers. That took 26s to preview for me. So I'd call this a method of
last resort. The rounding methods in BOSL2 are much faster, if you're able
to use them.
It also seems that bottomFillet() doesn't work correctly. I get no fillet
when I try to apply it to the original poster's prismoid example.

If the stepsize is the size of the layers, then when 3D printing the
result, there is no difference....
That said: lots of disadvantages remain. e.g. resin printers put
objects at an angle and have very high resolutions.

f equals m times a. When your f is steady, and your m is going down
your a is going up. -- Chris Hadfield about flying up the space shuttle.

There is no NEED for a mitre saw if you want to cut a 45° angle on a
2x4, but it sure is easier than using a handsaw.

Probably that is the error I mentioned b4. If it is, then It was an easy
enough fix.

You can do things with a handsaw, once you learn how to use it, that are
impossible with a mitre saw, and sometimes clamping the piece for the
mitre saw is a pita.

Of course, but If you are using the BOSL2 mitre saw, you still have the
handsaw in the form of OpenSCAD.
As I say, there is no NEED, but that's not why I (for one) use it.
