huge)

There MUST be a tool to engage with the two dimples that they all have
on the exposed end - but I've never been able to source one commercially
- so today I printed one on my Cetus 3D printer. Oh boy why didn't I do
it years ago - SO much easier

That's probably the first reasonable DIY use for them that I've come across.

Knock up a couple of dozen and stick them on eBay at a couple of quid a
time and see what sort of take-up you get.
