Fingerprintsensor Housing

Model------- Version 1 -------InfoThis is a holder for a fingerprint sensor I bought on AliExpress.Because I have place behind the wall, there is a part of the sensor that sticks out so it can't be mounted completly against the wall.Also the diameter of the sensor should probably be a bit bigger, I haven't changed it yet and not planning on it.Use a bit of sandpaper to make the hole bigger.How it's drawnI have experience with AutoCAD not only 2D but also 3D, as I'm new to 3D printing I haven't had the time to learn something new.Is this the most beautifull print?Not at all, circles are choppy, and I don't know how to fix it, there are other problems but in general it looks OK and works.
