Peace, mercy, and blessings of God be upon you. I present to you the well-known Ender 3 printer. The printer has many modified parts for its development, and some of them are shown in the display photos. The most important development 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. It is inside the small gray box. Among these additions: - Z-axis stabilizer - Fixed iron spring - Aluminum instead of plastic extruder - Changing parts in the head makes heating faster and better than the old parts - PETF tube withstands higher heat and does not melt over time And many other additions... As for the external parts: - There are approximately 30 nozzles with all sizes. - Screwdrivers and printer parts are available. - 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 small note, which is 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. The printer is for sale to the highest bidder, and offers below 300 SAR will not be considered.
