>I'll happily print you one for £25 :-)

Many thanks for the offer. Iive had a recommend for the MF Onyx - Markforged Onyx Nylon with chopped carbon fibres - so gone for that- https://markforged.com/product/onyx-filament/
Wonder if that filament would work in other printers??

It is for an AV item of kit - HDFury Diva and Vertex2 - https://hdfury.com/product/4k-vertex2-18gbps/. Once box, 500g or so, is slid in and cables connected, it should have a pretty stress free life. Just a little warmth at the display.

There may be others with HDFury gear in the same boat - I'd be happy to post on AV forum??
