Update on box stand

i updated the box stand as per the remix i previously made - there is a 120mm gap between the center of the two m10 nuts - in other words, it can take a spool of max width of 100mm, maybe a bit more.

The original (and rest of the stand parts) can be found here:

I made one for my printer (and now i am boxing my printer) so i needed something that can stand - ie i already have the rest of this, just needed a new base.
