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.

Hello , i like your design very much !
But when it was reddy from the printer i realize that mounting holes are not the
same as my openbuil Ox cnc .
my mounting holes are 40mm center to center .
is it possible that you can chance the distance from 20mm to 40mm
It would be very helpful , thanks in advanced .
kind regards stefaan
