Floor lamp base for LED v-profile with pockets for adding weight for improved stability

I wanted to use taller LED profiles, and so needed a way to make the base heavier and thus better suited for longer LED profiles.  I created cutouts in the original design to allow filling with something heavy - plaster, steel pellets, lead pellets, etc,. , and extended the sleeve that holds the v-profile to give the longer aluminum profiles some additional support. 

I also added a recess  in the electronics cover where an INMP411 digital mic  can be placed, for those people who want a sound reactive controller.

STEP file included for those who want to modify further.
