Makerbot Headphone Stand Remix

Version 003: Now with an option to make it really heavy

I have been using this stand for a while now, and two things have bothered me:
* I wanted points as feet so it would always stand well even on not-so-flat surfaces
* I wanted it to be a lot heavier. The wide feet don't make it prone to falling over, but it gets pushed around easily, and the headphones are significantly heavier than the stand itself, which is never a good thing really.

Recently printed an LED lamp and their design used 6 mm steel balls in the pedestal to make it heavy at the bottom, and that gave me an a-ha! moment. 6mm steel balls are basically AirSoft ammunition, and you can buy them in bulk for pretty cheap.

So now Version 003 has two parts: Main part and cover. Print both parts, fill the hollow section with steel balls, and glue in the cover. It's 10 degrees conical and should fit snugly, but I made it with a 0.1 mm offset so it sits a bit lower than flush, which is completely intentional and will no
