Upgraded Spool Holder (MOST Delta: Athena)

This upgraded spool holder is made to be fully compatible with the current wire holding mount hardware included with the Athena Printer. The edges are rounded instead of square for better rolling/sliding on the surface. Also the larger radius on the upgraded holder is stronger than the original spool holder.

Design and Printing

Design

OpenSCAD was utilized for all modeling operations.

Printing

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

Delta Dampener Installation
Placement. *Note: You may have to invert the printer to apply enough pressure.  
Fully Installed.  

Link to Files

The file repository is located on Thingiverse thing:1809228

Other Sound Dampening Techniques

  1. 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.
  2. Utilizing a heavy weight grease on the guide rods seems to reduce the vibrations of the quick bearing movements.
