Fusion 360 Parametric PVC Flange Mount (Schedule 40 1 Inch) + Countersunk Holes

In this Autodesk Fusion (Fusion 360) tutorial, you’ll learn how to design a strong, parametric 3D printed pipe flange mount for 1 inch Schedule 40 PVC. We start by confirming the nominal outer diameter (1.315 in or 33.4 mm), then build in printer-friendly clearance using user parameters so you can quickly tune the fit for your specific 3D printer. From there, you’ll create the flange base, extrude the sleeve, add countersunk screw holes with the Hole tool, and use circular patterns for clean, repeatable mounting points. Finally, we’ll add chamfers optimized for 3D printing so the part prints flatter and cleaner on the bed.

This workflow is ideal if you want a customizable PVC pipe mount, a 3D printable flange bracket, or a quick Fusion 360 parametric fitting that updates automatically when you change clearance, wall thickness, or flange size.
