Dustshoe vacuum connector

Introduction

For my homemade CNC router I created a dustshoe a while back. This is the connector to the hose leading to my shop vacuum cleaner for dust extraction. I printed it in black ABS with 0.2 mm layers. The design was made some years ago in FreeCAD, I don't know why I never uploaded the design, but here it is.

The connector fits on a standard vacuum hose of 40 mm diameter, with 2.5 mm pitch.
