The standard `mirror()` command works like this:
```openscad
#yrot(60) cylinder(h=50, d1=20, d2=10);
mirror([1,0,0]) yrot(-60) cylinder(h=50, d1=20, d2=10);
mirror([1,0,0]) yrot(60) cylinder(h=50, d1=20, d2=10);
```
BOSL2 provides shortcuts for mirroring across the standard axes; `xflip()`, `yflip()`, and `zflip()`:
```openscad
#yrot(60) cylinder(h=50, d1=20, d2=10);
xflip() yrot(-60) cylinder(h=50, d1=20, d2=10);
xflip() yrot(60) cylinder(h=50, d1=20, d2=10);
```
