Index Plate

Create custom index plates for use with dividing heads and rotary tables. All settings are customizable so this should work with many different dividing heads.

The default settings were designed to work with my 6" LW Chuck Dividing head.

This is my first openScad project so It'll probably change a little as I clean up the code.

Here are the variables used and the description :

Plate_Diameter = 127; // Diameter of plate in mm
Plate_Thickness = 6.4; // Thickness of the plate in mm

Index_Hole_Diameter = 3.7; // Diameter of plate holes in mm
Index_Offset = 6; // Distance from outside of plate for the first ring
Index_Row_Offset = 5; // distance between rows of rings

Mount_Center_Diameter = 29; // Diameter of mounting hole
Mount_Ring_Diameter=44.5; // Diameter of the ring used for mounting bolts
Mount_Ring_Screw_Inner_Diameter=6.6; // Diameter of mounting bolts
Mount_Ring_Screw_Outer_Diameter=14.25; // Diameter of head of the mounting bolt - user for counter sinking
Mount_Ring_Screw_Counter_Sync=2.7; // Distance from plate bottom for the counter sink
Mount_Ring_Screw_Count=3; // Number of screws used for mount

intervals = [33,31,29,27,23,21]; // divisions of each ring, These must be listed largest to smallest
