Printed in Ender-PLA using a K1C. In this case, we will use the 0.08mm preset for the K1C. The print takes just under 8 hours to complete.
The following settings were changed in Creality Print from the default options.

Quality

Ironing type: All top surfaces

This will give it a nicer, more premium look.

Strength

Sparse infill density: 5%

Sparse infill pattern: Cross 3D
This print will experience loads whenever there are coins going through it. To properly support it and save as much filament as possible, we use a cross 3D pattern for the infill pattern along side with 5% infill.

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 eight layers to be precise) print speed, we ensure that the first layer adheres optimally to the print bed.

Support
Enable support: Checked
Type: Tree(auto)
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.
