***TO INSTALL***
|

***USAGE EXAMPLE***
|
||
|
|
This generates a 75mm tall 2020 extrusion:
|
||
|
|
|
||
|
|
use <2020_profile.scad>
|
||
|
|
|
||
|
|
linear_extrude(height=75) 2020_profile();
|
||
|
|
|
||
|
|
|
||
|
|
***NOTES***
|
||
|
|
|
||
|
|
Please be aware that there are many different variations in real world aluminum extrusions. Differences in tolerances, minor details like corner bevels, and even major variations in the interior cross section are common. This particular model is very basic with square edges.
