On a number of occasions, I have had the need to print a simple pipe reducer. This customizable design allows creating three types of reducers.

• One: Supply the inner diameter for both sides
• Two: Supply the Inner diameter for one side and the outer diameter for the other
• Three: Supply the outer diameter for both sides

The configurator allows customization of wall thickness, the height of each individual section as well as the diameters on each side.

Open in Customizer and provide your own settings. https://www.thingiverse.com/apps/customizer/run?thing_id=2461538
