The Z-axis motor mount of MK4 is not compatible with just changing the rod diameter to 8mm, as the width of the rod axis is different from MK3. Therefore, I have remixed the MK3 mount to resemble MK4. You can use the X-axis parts and the Z-axis top without any modifications. By replacing this parts, you can expect an improvement in rigidity.

Print Settings:

  • Material: ABS
  • Layer height: 0.20mm
  • Supports: no
  • Perimeters: 3

Note:

  • All the screws used can be directly used from the stock ones.
  • I recommend printing with PETG or ABS. Please do not use PLA as there is a risk of deformation due to the heat from the bed.
