Goals

This document is where we are going to collect example items you can use to improve your CAD skills.
You should work to CAD each item as accurately as possible
You should attempt to use as few sketches and features as required.

this doesn’t mean putting everything in one sketch when it doesn’t make sense to do so.
Mostly it means you can fillet multiple edges with the same feature, or extrude multiple parts of the same sketch, etc.

Most of these examples are found from various online sources including reddit.com/r/cad
For many of the small parts in here you may 3D print after you complete them.
