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:

• On Google drive
• Bill_of_material.xlsx

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
