This machine was designed with the goal of being fully 3d printed. The price for this machine (Excluding control electronics) is about 600$. The frame is made up of 2020 and 2080 extrusions. The motion is handled by MGN15H linear rails, ball screws and Nema 23 Stepper motors (Nema 17 for Z-Axis). Due to this there is no play and the entire machine is very rigid and accurate.
It has a usable build volume of 360x360x75mm
If interested about the build process, I made a video about that: https://youtu.be/GlJae67H9mo

Update: I've added the parts used for the electronics
Warning: mount_01 leaves mains voltage exposed. Don't use it if you don't think of fixing it.
