This project sprung out of a desire to make a quality and long lasting memorial for a late friend. Her family couldn't to buy a marker, so I offered to help. After having less than desirable results using a diamond drag bit, I was sure there had to be a better way. Some research into the granite engraving world found some extremely expensive machines and specialty bits that were cost prohibitive for my needs. I borrowed a key integration into many of their designs: an angled engraver that allowed high-speed diamond burs to be used as they were intended.

This led me down an extensive path of design and testing. I found that tool angle was critical to prevent excessive wear, and there also needed to be just the right amount of flex in the mounting design to prevent snapping the bits when plunging. The final problem to overcome the was the harmful dust this process created.

After over a dozen design iterations I arrived at this. While i'd still consider it to be in "beta", I could not be happier with the results!

I've achieved reliable engraving at over 160ipm, with deep, clean, and crisp lines. It requires NO MODIFICATION to the existing Shapeoko router mounting bracket (of 69mm diameter) It incorporates an easily adjustable dust collection shoe that is compatible with both 1-1/4" and 2-1/2" vacuum hoses, and uses readily available and inexpensive rotary diamond burs.

It works on the hardest materials, including: Steel, Titanium, Stone, Glass, Porcelain, Marble, and Granite, and DOES NOT require any additional air or coolant systems!

The mount comes pre-assembled ans can be ready to use within minutes of arriving at your doorstep. Flex shaft can be purchased separately or can be used with most tools with ~20mm diameter. Here is a $20 rotary tool with compatible flex shaft: https://www.amazon.com/dp/B003BYRFH8/ref=cm_sw_em_r_mt_dp_U_DuPpDb3TH7M70

Save yourself the time, frustration, and wasted materials by buying my tested and proven design, and expand the capabilities of your versatile machine.

While it is 3D printed, I put extensive effort into the design to ensure optimal material strength, and only use quality filament. Each print takes over 12 hours! I'm so certain of it's durability that If any part of your mount fails under normal use within the first month, I will replace it free!

This tool will pay for itself in it's very first use... Mine saved me $200 on my first project! *Please respect the effort I put into this design, and don't copy or share the files online. *
