CNC Spindle Mount for Openbuilds

youmagine

Here is the mount I am using on my SMW3D R7 CNC. It securely holds an 80mm OD water-cooled spindle to either an 80mm section of openbuilds v-slot or, as in my case, C-beam. I also have a 65mm OD version available for those with smaller-sized spindles. To help others use and modify it as needed, I am including the STL files, original SolidWorks models, as well as step and x_t models. The mount clamps down using three 5mm screws, and the pockets in the back half are designed to accept openbuilds t-nuts, which distribute the clamping force. I printed mine in PETG, with 5 perimeters and 50% infill. Despite being a printed part on a CNC machine, this mount is remarkably tough due to its PETG construction.
