Modular Plastic CNC

The sleds

The slide provides the movement on the individual axes. I would like to show how one of the sleds is built using the example of the small slide with a copper nut.



For the little sled with spindle nut mount you will need the following parts, nuts and screws:

  • 16x M4 nuts
  • 2-4x M3x10 screws
  • 1x copper nut
  • SledMiddlePart35WithCopperNutMount


The middle part of the sled with copper nut mount should be assembled as shown. If you plan to expand your CNC machine, you can also fill all the nut traps.
If you plan to attach the copper nut from below side, you can pierce the screw holes with a screwdriver. The plastic is only one layer thick at this point.


Next you will need the following components:

  • 1x complete  SledMiddlePart35WithCopperNutMount
  • 2x SledBearingMount
  • 8x ball-bearing 5x13x4
  • 8x M4 nuts
  • 16x M4x20 screws


Now the two SledBearingMount parts are screwed to the middle part. Only then the ball bearings can be placed and fastened. The ball bearings should not yet screwed on completely, as the running ability of the slide still has to be tested and adjusted.


What kind of sleds are possible?
