Mini Milling Machine

I built this Mini (Micro) Mill mainly for machining cooling blocks / heat exchangers for custom computer cooling loops. It is rigid enough for light cuts in soft metals such as aluminum, copper, brass, etc. Could also be used for PCB milling. The maximum travel in my design is approximately 100mm x 100mm. I did not need a larger area for my application and keeping it small allows for better rigidity. Most files are in Fusion 360 (.f3d) file format. Please reference the Fusion 360 Assembly file (.f3z) for showing how things are supposed to fit together.

I consider this an MPCNC (mostly printed CNC) design because you do not need to purchase or create specialized/custom components if you don't want to. All the parts can be bought off the shelf or printed (although some of the printed components should be eventually replaced with metal for the best performance). Keep in mind that plastic is relatively flexible and will creep over time, so it is not the best material in this application
