How to Draw a Basic Bolt with a Real Thread in FreeCAD !

I show in this FreeCAD tutorial how you can simply draw a basic bolt with a real thread that can be 3D printed or otherwise further processed.

It would be very nice if we could discuss there everything about Stirling engines, 3D printing and more, thank you very much Baptiste.
FreeCAD has evolved rapidly recently.
To make use of the new features, I’m doing a tutorial here to show you how to create this threaded bolt in just a few steps—for example, for 3D printing.
The new possibilities in FreeCAD from Version 1 are fantastic, and I use it extensively to create all my models for the thermoacoustic Stirling engine.
To help you take full advantage of the open-source CAD system FreeCAD, follow my new video series of tutorials.
Today, we want to design a simple bolt with a 1/4-inch internal thread and a square head. With the right approach, this is done in a few simple steps.
From the finished model, you can now create a manufacturing drawing, a CAM file for CNC machining, or a file for the 3D printer.
I like to use the .obj format, as it saves radii and details even more precisely than the .stl format.
We can now load this file into the slicer and prepare it for 3D printing.
My print turned out very nicely and fits perfectly, and I hope this tutorial was helpful to you.
I look forward to your feedback and questions in the comments, so I can address your requests in the future.

Thanks for watching!
