Optical Illusion Donut 1 - Dễ in

In South Vietnam, we often say things are easy to print, like this model!

Size: 110.63mm x 200mm, 2mm thick. Around 3 hours to print on my Geeetech A10T.

For printers with multiple extruders, just split the model into parts. Then, choose the parts for your second color. Usually, the first part is the base color, and all other parts are the top color.

For printers with a single extruder, here's how we do it:

1. Slice the file.
2. Select layer 6 (at 1.2mm height).
3. Right-click the + icon.
4. Select 'add custom G-Code'.
5. Type M25 (Pause SD Print) - this works with Marlin2 Firmware.
6. Re-slice the file.

Easy peasy, right?
