Vibration Dampener (MOST Delta: Athena)

This vibrational dampener was designed to reduce the vibrational noise of the MOST Delta - Athena during printing. This is achieved by reducing the motor-end contact area with the table / desk and provides a "spring" like action. Most notable differences will be seen on non-rigid tables / desks.
Design and Printing[edit | edit source]

Design[edit | edit source]
OpenSCAD was utilized for all modeling operations. The MOST-Athena GitHub file repository is located here. The motor-end assembly was imported into OpenSCAD and the part was designed to accommodate the geometrical constraints of the parts provided to MY4777.
Printing[edit | edit source]
The stiffness of the component is driven by the infill percentage. Adjust as necessary to achieve your desired characteristics.
Print Parameters Utilized:
- Layer Thickness: 0.2mm
- Skin Thickness: 1.0mm
- Top/Bottom Thickness: 0.5mm
- Temperature: 180C
- Speed: 80mm/s (60mm/s outer contour)
- Flow: 100%
- Infill: 50%
Installation[edit | edit source]
The model is designed to snap fit onto the bottom of the motors ends. Print out qty. 3 of the STL and install as shown below.

Other Sound Dampening Techniques[edit | edit source]
- The default U,V,W motor acceleration is 4000mm/s. You can uniformly decrease this to any lesser value to quiet the quick movements of the motors / bearings.
- Utilizing a heavy weight grease on the guide rods seems to reduce the vibrations of the quick bearing movements.
