What I liked in this book

A good tutorial book for beginners with OpenSCAD. David Leithauser covers the basic principles of constructiong 3D objects by using a descriptive language. The reader learns how to create simple shapes, text and even 2D objects and extruding them to the Z axis.

There are also good chapters about how to create Joints, Screws, Snap-Ins and Gears. We also learn about the basic math functions.

After the first chapters I was able to create my first spare parts for Ikea shelf carriers and my postbox.

What I was missing

I would have liked to read about a few things more in this book:

First, how to get help online if you have a specific question or problem to solve. Are there any OpenSCAD user groups, facebook groups or whatever to ask for help?

Then I would have liked to get a bit deeper than just scratching the surface. For example, one of my basic questions regarding OpenSCAD is how to get round edges on my 3D objects. I heard that there is a "minkowski()" function that can help to to do this, but I really would have liked to see an example on that as well. Or on other functions that at the moment I don't even know about.

The missing parts led to 4 instead of 5 stars, nevertheless, the book is highly recommended for beginners. I read the printed book which comes from Amazon fulfillment and was printed in black and white (no colors except of the cover), but that wasn't a problem.
