Bill of materials

This page includes an aggregated overview (incl. images) of all the parts needed to build the CNC-machine. To get a better understanding of how the parts are used (additional comments etc), check the following detailed spreadsheet:

The 3d-printed parts were printed in standard PLA using:

  • 30% infill
  • 4 top solid horizontal layers
  • 4 bottom solid horizontal layers
  • 4 perimeters

The complete PrusaSlicer config used can be found here: prusa_slicer_config.ini
