Printed in Ender-PLA using a K1C. In this case, we will use the 0.08mm preset for the K1C to preserve that sharp edge detail. The print takes just over 30 minutes to complete.

The following settings were changed in Creality Print from the default options.

Strength

Wall loops:3

Sparce infill density: 20%

AI Infill: Checked

We want to make sure that the box cutter retains structural integrity when it is in use. We will let the AI help us out to provide support in an efficient manner using the default infill pattern (Grid) as we are using 20% infill (The default is 15%). The AI is only able to use the default grid infill pattern with infill densities of 20% or above. Increasing the number of walls to 3 adds to the rigidity of this print.

Speed

First layer: 30 mm/s

First layer infill: 50 mm/s

Initial layer travel speed: 50%

This is the number of top interface layers: 4

By reducing the initial layer (the first four layers to be precise) print speed, we ensure that the first layer adheres optimally to the print bed.

Support

Enable support: Checked

Top Z distance: 0.3mm

Bottom Z distance: 0.3mm

There are some overhang areas that need to be supported or otherwise the print will fail. Increasing the Z distance allows the supports generated to be removed much easier and prevents them from fusing with our print.

Other

Brim type: No-brim

There are no bed adhesion concerns with this print.
