I cut an old aluminum arrow shaft I had into 4 toggles and its worked well for quite a few years.
I thought it was the same as an arrow shaft, but the wall must be much thinner and less robust than an arrow.

I just measured, it is 7mm OD and 6mm ID which unless my thinking is wrong, the wall thickness is about 0.5mm.
