|

|
*
|

|
* Drop this script somewhere where OpenSCAD can find it (your current project's
|

* working directory/folder or your OpenSCAD libraries directory/folder).
|
||||||
|
*
|
||||||
|
* Add the line:
|
||||||
|
*
|
||||||
|
* use <knurledFinishLib_v2.scad>
|
||||||
|
*
|
||||||
|
* in your OpenSCAD script and call either...
|
||||||
|
*
|
||||||
|
* knurled_cyl( Knurled cylinder height,
|
||||||
|
* Knurled cylinder outer diameter,
|
||||||
|
* Knurl polyhedron width,
|
||||||
|
* Knurl polyhedron height,
|
||||||
|
* Knurl polyhedron depth,
|
||||||
|
* Cylinder ends smoothed height,
|
||||||
|
* Knurled surface smoothing amount );
|
||||||
|
*
|
||||||
|
* ...or...
|
||||||
|
*
|
||||||
|
* knurl();
|
||||||
|
*
|
||||||
|
* If you use knurled_cyl() module, you need to specify the values for all and
|
||||||
|
*
|
||||||
|
* Call the module ' help(); ' for a little bit more of detail
|
||||||
|
* and/or take a look to the PDF available at http://www.thingiverse.com/thing:9095
|
||||||
|
* for a in depth descrition of the knurl properties.
