Just like putting whip cream on your breakfast waffle. Printers are stupid and do not know what they are doing, they only know how to get to a specific coordinate... Read More

Before we slice we need to have a digital 3D model. Either download one online or build your own with CAD software. Then we can import it to a slicing software and export it as Gcode file into an SD card. The SD card will be plugged into the printer for the printer to read the file... Read More

In this post, I will be talking about some of my personal experiences and what I learned from those experiences.

I also 3D printed my own laptop stand since almost all the time I have to look down and work on my laptop for a long time. And this is bad for my neck and can develop neck pain... Read More
