YouTuber 3D prints low-cost CNC milling machine based on a Dremel

YouTuber Nikodem Bartnik has designed a particularly affordable CNC router based on the Dremel multifunction tool. He now demonstrates the printing and assembly in a video. The STL files for the 3D-printed parts are freely available.

The concept uses low-cost components such as profile rails, spindles and controls from the 3D printing sector. The detailed assembly instructions should also make it easy for beginners to replicate. According to Bartnik, the working range and spindle performance are completely sufficient for simple engraving and milling work.

The hobbyist quotes a cost of around 150 to 200 euros for all the components. Only the spindle and control electronics need to be purchased separately. He published detailed instructions on Instructables. A compilation of the 3D models required for the construction is available free of charge at Thinigiverse.
