This backstand was a cheapie bough on eBay from the US for about $12.00 USD. It needs to be mounted on a base, in this case a piece of flat hardwood, but it puts industrial thread within the range of folks who use semi industrial sewing machines.
This version will take 4 different cones, handy if you need to keep a range of colours available.
The thread guide is on a telescopic arm that can be raised high enough to pass the thread down to a sewing machine.
This is how I use it with one of my old Elnas.
