Yamaha TRBX505 broken nut

[Willerdlongneck]

I broke the nut on my 5 string Yamaha TRBX505 and am looking for a replacement nut. Is the nut brand Yamaha, or is it a third party nut?
I understand from my internet searches that the nut is made of urea. Should I be looking for a replacement made of that same material, or is there better ones?
Any ideas of where I can get a replacment (original style or after-market)? It would be nice if I could get it in Canada or if it had free shipping to Canada.
Here's the dimensions if that helps: 42.6mm/5mm.
Thanks.

Pics? I split the nut on my Yammy 5er trying to force-fit a tapered string through a slot. The late, legendary Jim Mouradian was able to fix it with glue (don't know which), a clamp and a little time.

Here are some pictures. I don't think glue would be strong enough for this job. Besides, I lost the piece that broke off.

If you have a skilled tech nearby, they can fabricate a new one from any number of materials. I'm of the assumption you want something to "plug 'n play" > pre-slotted, same dimensions for a quick install. Yamaha has pretty decent customer support...here ya go:
