Root 3 CNC - Building the Spindle Mount Assembly

To start the spindle mount assembly, the following parts were used:

• 2x MGN12C 80mm Spindle Mount 3D Printed Parts
• 2x M3 x 35mm screws (0.5mm threads)
• 4x M3 nylon lock nuts
• 2x Brass T8 Trapezoidal Screw Nut

For each of the 3D Printed Parts, fasten the T8 lead screw nut with 4 screws and lock nuts.

To combine the two parts into one spindle mount assembly, the following parts were used

• 2x High-Strength Steel Threaded Rod 10-24 Thread Size, 4" Long
• 8x 10-24 flanged lock nuts

Insert the threaded rods, and attach on both ends with a flanged lock nut:

Add the second spindle mount and surround with flanged lock nuts.  Temporarily add the 8mm lead screw to check alignment, and then tighten all nuts.

The spindle mount assembly is now ready for mounting on the Z-Axis:
