Some parts of Co Print are produced from PLA plastic using 3D printers. The reason these parts are made of plastic is that they can be easily and cost-effectively replaced when worn out. You can easily produce and use the plastic parts of Co Print using the 3d printers you have.
The slicing program we recommend to use for printing stl files is Cura.
Place the stl file given for 7in1 vertically on the table with the tip of 7in1 facing up. Apply support to the surfaces at the bottom by activating the Tree Support feature. The lower you keep the layer thickness, the better your print quality will be and the more likely you are to get a smooth and stable part. For the 7in1 module, 0.1 Layer thickness, 20% fill and PLA filament are recommended.
Tolerances are important when printing Co Print Printable Parts. Your printer's filament calibration must be correct in order to accurately measure the parts.
