RepRap Foot Vibration Damper
by Conseils, published
This item is a derivative of a vibration damper (dampener in american). Vibration from the 3D printers mechanisims are absorbed by the springs formed in the curved element of the foot. The reduced noise and vibration harshness leads to significantly quieter machine operation and a happy family life!

Background Vibration from movement of the system is transmitted through the feet of the device. In my particular installation Huxley #710 is located on a box 1.5mÂ² covering the stairs below. The resultant chamber underneath acts to resonante, amplifying the vibration into a rather loud drumming.
The addition of the vibration damper significantly reduced the noise levels from the device!
Derivative changes Two additional extrusions have been added to retain the anti vibration feet on the bottom of RepRap Pro device such as Huxley #710. This means that for cleaning and servicing the feet stay in place when Huxley #710 is moved.
To enable the changes to the original model, it was converted from STL to STEP and then modified. You can find the modified STEP file here as well as the un modified file.
A description of how to do this for yourself can be found here northernhope.blogspot.co.uk/2012/09/stl-to-step.html
TIPS Make sure that your settings are sufficient to create solid walls. There is quire a surprising mass on each foot and they need the stiffness created from both walls well attached to each other. Additionally with time there will be permenant deformation if the walls are not attached which is likely to lead to failure. The orignals are now 8 months old and still work perfectly other than constantly falling off when I need to move Huxley #710 for cleaning and maintenance.
