| Module | Description |
|:--- |:--- |
| ```drill(r, h = 100)``` | Make a cylinder for drilling holes suitable for CNC routing, set h = 0 for circle |
| ```drill(r, h = 100, center = true)``` | Make a cylinder for drilling holes suitable for CNC routing, set h = 0 for circle |
| ```poly_circle(r, sides = 0)``` | Make a circle adjusted to print the correct size |
| ```poly_cylinder(r, h, center = false, sides = 0)``` | Make a cylinder adjusted to print the correct size |
| ```poly_drill(r, h = 100, center = true)``` | Make a cylinder for drilling holes suitable for CNC routing if cnc_bit_r is non zero, otherwise a poly_cylinder. |
| ```poly_ring(or, ir, sides = 0)``` | Make a 2D ring adjusted to have the correct internal radius |
| ```poly_tube(or, ir, h, center = false)``` | Make a tube adjusted to have the correct internal radius |
| ```slot(r, l, h = 100)``` | Make a horizontal slot suitable for CNC routing, set h = 0 for 2D version |
