Many thanks for that. Yes, I have now found it and turned it OFF !!!
I only found out about it as I started getting plaintive PMs from people wanting to buy a latch to repair their breadmakers, but confused as no "Buy it Now" button was showing.
The latch is one of my little pleasures, having over a number of years helped over 300 people keep their otherwise functioning machine up and running properly.
And it's a nice party conversation piece. Even now people, who know a bit about 3D printing from all the filament printing 'bot machines being so prominent, are still amazed to see something printed in real metal as an affordable and practical object.
BTW these people I show it to include machinists from our Physics mechanical workshop at Imperial College (where I work), who do really wonderful stuff and normally are the ones who know all there is to know about making things in metal.
My background is electronics and instrumentation, so it is nice to be ahead of the curve in mechanical matters once in a while
Best,
Susan.
