The Cairo Mini 3D-Printer
We Are Introducing The First Egyptian Truly Open-Source 3D-Printer
The Cairo Open-source CNC Machines
It is a project started by Ahmed Ibrahim as a move to spread the digital fabrication technology among everyone and anyone. That came from his fascination with how fast and easy these machines can turn ideas and sketches into reality and prototypes with almost no need for a previous tech background. The main goal of this project is to make easy-to-build, fully open-source, truly reproducible CNC machines that anyone can reproduce. Using popular, easy, and available components in the Egyptian market. Not only open-source! but also fully documented. To make it easy for anyone with or without technical knowledge to follow along and make his/her own machine. In this page, you will find an up-to-date parts list, fabrication, design source files, and full assembly guides.
The Cairo Mini 3D-Printer
We are introducing the Cairo Mini 3d-printer! It’s a DIY fully Open-source Reproducible 20x20cm 3d-printer. The original goal of the Cairo Mini 3d-printer is to create a low-cost 3d-printer below 220$(1100 LE). That anyone can build with ease.
Parts List
Below you can find all the parts that I used to build the Cairo 3d-printer. The file is divided into mechanics and electronics you can easily print, export, and open on your computer you can find it here!
Files
Below you can download DXF files, you can use those files to laser cut your 2D parts. Those should be cut out of 6 mm acrylic(you can use 6mm wood instead but we don’t recommend that). Choose your preferred colors and be unique 😉
If you are going to order or manufacture that on your own just simply send those files to any makerspace with a laser cutter machine. All DXF files are in mm.
Part Name | Quantity | Material Thickness |
2020 Bed Carrier.dxf | 1 | 6 mm |
X-axis idler pulley holder.dxf | 1 | 6 mm |
X-axis motor holder.dxf | 1 | 6 mm |
Y-axis belt fixer.dxf | 1 | 6 mm |
Y-axis motor holder.dxf | 1 | 6 mm |
You will also need some 3D printed parts, you can find all STL files in the ZIP archive below. Settings I use to print them: 40% infill, 0.2 mm layer height (with 0.4 mm nozzle).

We always get amazed by the community builds! We are encouraging You to make edits and fork our design. Here you can download the STEP file of the Cairo Mini 3d-printer.
Cairo Mini 3d-printer is running on Marlin 2.0x that’s cleverly customized to best fit with the machine hardware. You can download our customized Marlin 2.0x version down below.
Feel free to download the Cairo Mini 3D-printer Ultimaker CURA profile. that will help you to get your CURA software ready to slice for the Cairo Mini 3D-printer seamlessly.
