Peace, mercy, and blessings of God be upon you. I am offering for sale the well-known Ender 3 printer. The printer has many upgraded parts for improvement, some of which are shown in the display photos. The most important upgrade is the installation of the Klipper system, the most famous system for 3D printers, which allows you to increase printing speed as you wish and send files directly over the internet without an SD card. The system is installed with a small computer called Orange Pi, which is inside the small gray box. Some of these additions include: - Z-axis stabilizer - Fixed steel spring - Aluminum extruder instead of plastic - Changes to the hotend parts that make heating faster and better than the old parts - PETG tube that withstands higher temperatures and does not melt over time And many other additions... Regarding the external parts: - There are approximately 30 nozzles in all sizes. - Screwdrivers and printer parts are included. - Three colors of filament (printing threads) for testing. - A spiral fan if you want to upgrade the cooling. - BL Touch bed leveling sensor is available but not yet installed. In conclusion, the printer is complete, lacking nothing, and mechanically calibrated in the best possible way. There is a minor note: some scratches on the print bed as a result of learning on it, but they do not affect printing. It can be replaced for only 30 SAR. I hope someone who understands printers will take it. I want 500 SAR for it, and the current offer is 400 SAR. The sale is urgent.
