Magnetic dovetail guide derived from the excellent design by David Barron:

• Original Guides
• Davids Blog

The design has been modified to accommodate 3D printing, the primary difference being that this design is only single handed. This was done so that the guide face is flat, and so that the magnet holes do not require support. In addition to this, the guide face is smaller than Davids original design to accommodate a western dovetail saw.

For the ratios provided, printing with supports should not be required.

OpenSCAD source is provided, allowing you to choose:

• Left or right handed
• Dovetail ratio
• Number and size of magnets

I'm a total novice when it comes to hand tools, this guide has been amazing in helping me achieve decent results first try!
