This is a protective front cover for the Revopoint Inspire 3D scanner. If your printer's extrusion flow is calibrated, it should friction fit pretty nicely.
Update 10/11/23:
Added a 2nd stl with a looser fit (scaled to 100.5% per user feedback). If you find that it fits a bit too tight for your liking, you can either scale the original to 100.5% in your slicer, or download the pre-scaled version included here named “Revopoint Inspire Cover - Looser.stl”
