The file 'Lil’ Blue – The Desktop CNC Laser 3D Printer Model' is (zip,txt,xlsx,lbset,STL) file type, size is 8.2MB.
This is my Lil' Blue CNC Laser. I have been wanting to make one ever since I turned my 3018 into a CNC machining tool only. I didn't like how the 3018 was so slow and sloppy when it came to the motion system, especially when you tried to ramp up the speed for laser engraving/cutting. I started this project about a week ago, and seems fairly complete now.
I used pack and go, so you can import this assembly into Solidworks and make it your own! Or, you can print the .stl files, buy the components, and have yourself a sweet little CNC laser!
