Enclosure Bottom Support

I've always sworn by paver stones, and when I received my Prusa Enclosure, I still wanted to use it, but they're very heavy and I was concerned about the bottom panel incurring high stress and sagging, so I made this simple bottom support. 

Design Theory

It's a simple sandwich design (see photo): 2 identical printed base supports and a piece of foam. 

The foam acts as a compression support and enclosure resonance attenuator.  This is one of the reasons why the included enclosure feet have foam pads.  Just throwing a chunk of solid metal/plastic/wood under the enclosure will cause vibrations to resonate outside the enclosure. 

Build

1. Print out two of the base supports.
2. Cutout a piece of foam that's 6.75x6.75"x.64" (171.45x171.45x16mm) 
   • I used spare Pelican foam I already had, which can be purchased on Amazon
   • Similar foam could be sourced at arts and craft stores
3. Glue foam to supports (optional, but makes it easier to maneuver)

Usage 

1. See second photo for diagram and dimensional notes.  The takeaway here is you need to have the support+foam+support thicker than the distance from the surface to bottom of the enclosure.  This “extra” distance depends on the density (squishiness) of your foam.  
2. See second photo for second important note: do not allow the foam to compress so much that the supports touch - there must be a gap otherwise adequate support isn't supplied and vibrations will resonate.
