I upgraded my 3D printer this week by replacing the old hot end with an upgraded version and switching to an all-metal extruder. The extruder upgrade took about 15-20 minutes, while the hot end replacement took just over an hour. Despite not consulting any tutorials, I successfully documented the printer’s setup and reassembled it without any issues, which was quite satisfying.

I find it interesting to disassemble and explore the internal components of various devices to understand how they work. At work, I often dismantle old IT equipment before it’s retired, gaining valuable experience in handling screws, ribbon cables, and other peripherals. This hands-on practice has enabled me to perform a range of DIY fixes, such as replacing laptop screens, batteries, repairing broken touchpads, and replacing worn-out keys.

Additionally, I’ve had opportunities to repair several model printers that were returned to us due to broken parts or couldn’t be redeployed. In such cases, I salvage usable components to fix other printers with similar issues, minimizing waste and maximizing the utility of our resources.

I am finished with all the reading for my computer forensics course. I am now working on two projects that are due for the class and preparing for my final exam in the course. I am hoping to finish the course this weekend.
