Thanks for downloading my Diamond drag engraver 3D printable holder. This can be mounted to any 3axis CNC, 3D printer or robot to insert a 3.175mm diamond engraving bit.

I purchased mine from Aliexpress... (non affiliated link) https://www.aliexpress.com/item/32738578856.html

you will need to clean out the hole for the engraving bit to inserted. Please ensure that it has a very tight tollerence, otherwise the bit will move as you engrave and impact final result.

When Printing: Please ensure that you print on high quality resolution (0.12 layer height if possible) to ensure the the threads print correctly.
