Imperial Module for OpenSCAD

thingiverse

I'll see code like this often: ``` scale(25.4) cylinder(d=1/2, h=5/8, $fn=64); ``` ...to make parts in inches. OpenSCAD thinks it's making tiny parts 25 times smaller than they are and generates minimal detail unless forced, so I jam $fn into every statement. I can override $fs to fix that: ``` for($fs=$fs/25.4) scale(25.4) cylinder(d=1/2, h=5/8); ``` This gives me a sane number of fragments without forcing it! If I put this in a handy module, I get: ``` imperial() cylinder(d=1/2, h=5/8); ```
