This design was inspired by Nikodem Bartnik's project in order to create a machine as rigid and aesthetic as possible by using parts of 3D printers I already had. The result is much better than I expected!
For more photos and videos of the machine, visit here.

Some notes:
- The links in the BOM will bring you to the most appropriate items for the printed parts. If you choose to order from another source - check the details and measurements carefully!
- The STL files are optimally oriented for printing, and have small additions designed to reduce the amount of supports - you may need to clean some parts and re-drill some holes after printing.
- Do not forget to replace the springs in the nuts of the lead screws with those in the BOM! This will greatly upgrade the performance of the Anti Backlash nuts. I also recommend using POM nuts - I replaced to these after the first assembly and the movement is significantly smoother and quieter!

Special thanks to @SanglierLab_572946 for sharing a very helpful assembly guide.

For wiring and GRBL installation on the Arduino, you may also find this video helpful.

I have added a step file of the whole machine so that you can edit it according to the parts available for you.

If you find any problem with files or the BOM, please let me know!

Enjoy and share your CNC!
