BOSL2 cylindrical_extrude()
Is there a module or a function that can do what this does using a 3D
object instead of a 2D object? In other words, is it possible to wrap a 3d
object like a simple thin plate around a cylinder or a sphere? Would there
be something that can be used in the attachments feature?
I answered this question already: BOSL2 vnf_bend() can do it, but you
have to have a VNF and not a 3d geometrical object. If you have a
geometrical object, wrapping it around a cylinder would require
chopping it up into sections and moving them into position. It's
possible in theory, but would be really slow and probably would be
hard to avoid a stair-step ragged edge. Someone else posted about
having attempted this approach and abandoned it.

I must have missed that answer. Will look into it. Thanks!

The best way I've found to do this is to use https://3dp.rocks/lithophane/
to create an appropriately-curved piece, generate the rest in OpenSCAD (or
whatever) and use Meshmixer to combine them.

Feel free to develop your idea (maybe an example?)

Funny thing ... I've had that *3dprocks *website in my favorites bar for
a long long time ... haven't used it in a year ... forgot all about
it. *Meshmixer
*I do use, but only for *plane *cutting moulding strip patterns to exact
lengths in order to duplicate their patterns end-to-end for a final length
for the CNC.
