About this 3D model

Hi all, I've been developing an add on for my ER11 Spindle Motor, it's still in early stages as I have been developing this piece by piece, I have trialed this with great success. Will be adding all the files later if anyone should be interested in this. Also adding some video trying to explain what I have managed to create. The basics of this adapter was to precision engrave by using a depth gauge so the engraving tool does not cut too deep into the material. If anyone is interested in this let me know and I will start posting more about this adaptor.
