Foot for 2020 CNC frame

thingiverse

I've been experimenting with flexible filament (TPU) designs to effectively decouple my CNC machine from its rigid surroundings, thereby reducing unwanted vibrations. This design represents the current state of my efforts and has proven to be quite effective. Flexible filaments like TPU are surprisingly soft, making them a perfect candidate for creating dampers. However, they can still exhibit rigidity in smaller models such as this one. To achieve better vibration reduction, I plan on investing more time into designing optimized dampening systems in the future. Nevertheless, I believe this design has potential and is worth sharing. It can be printed using rigid plastic (e.g., ABS, PETG, PLA) to create a simple frame foot, although it won't provide any vibration-reducing benefits if used in this manner. I've included the OpenSCAD file for those who'd like to modify the design to suit their needs. When printing with flexible TPU filament, I found that using 10% infill density resulted in a fairly pliable material, which appears to be an optimal value for my application but can be adjusted to achieve varying levels of rigidity.
