I've designed a 65mm spindle mount to fit a Shapeoko2! I'm using this mount to hold a Chinese water-cooled 65mm AC spindle.
You can learn more about this mount by watching the videos I made about it:
The mount solves the following problems:
- Mount holds the spindle securely on the z-axis
- Mounted spindle clears the motor mount at the top of the z-axis.
- Mount fits onto the existing z carrage and does not add undue angular load to the z-axis.
- Mount is 3D printable and requires only minimal hardware to install. (M5 bolts of varying lengths)
- Mount is sized correctly to account for ABS shrinkage.
- Mount holds a laser diode for help with centering.
- Mount integrates with a 1.25" vacuum hose and provides dust-collection at the bit.
I've added a new dust-foot, called the Dust Boot. It is an alternate version of the dust-collection foot. This version doesn't restrict air-flow as much, but it does obscure more of the cutting head. I think its better at containing chips and fine dust, but you be the judge! For extra-credit, try adding a strip-brush to make the seal even better!

- These parts are designed for ABS printing. All of my testing for size/shrink has been done with ABS. It may work with PLA, your mileage may vary.
- Printing with rafts helps keep the build-plate side from being deformed during printing.
- No supports needed.
- The DustFoot has two triangular supports built into the design. These should be detached after printing.
- Tap the four outside holes in the face of the mount body.
- Connect the body to the carriage using M5 screws with nuts and washers on the back.
- Connect the clamp to the body using M5 screws, clamp down the spindle.
- If attaching the dust-collection sleeve, Tap the four holes on the left-side of the mount body.
- Insert a 9mm laser into the hole on the bottom of the body, pass the power wire upwards to the top of the mount.
- CA glue is your friend. Go nuts.
