Spool3D in Calgary sells sheets of FR4 (the flame resistant version of G10) that are bonded to spring steel sheets. I use with a few drops of the nano polymer adhesive they sell but would probably be fine without (A few drops in IPA seems to do the trick for ABS, lets me spread it extremely thin). I used Buildtak for a while and their surfaces are great, but this was a lot cheaper and extremely resistant, plus I like the surface finish it gives (Also I can source domestically, partly the reason I switched)

That’s the predominant one in Canada too, at least in my experience.

Goes with a Chipper Shredder (Woodchipper), sure there’s probably other things named the same way.

I did some testing for some parts for my dad, he keeps bees and lost a shaft support for one of his tools when he was reassembling it, he whipped up a replacement and fired me the stl when I was talking about my printers.

Printing with the shaft in the z needed a lot of supports,

laying it on its “back” was by far the easiest, outside of the support looked a little gross, could have benefitted from supports. Did them all in petg, gave them all to him just so he can get a feel for what 3D printed parts look like as he’s interested in getting one himself (trying to sell him on a v0 if he’s not sure, but kinda thinking about doing a trident)
