It’s probably made of acetal, sometimes known as Delrin. Fusion 360 cad software has a gear profile generator add-on so if you can work out what the gear tooth profile is modelling a new one is fairly simple. The tooth profile is most likely to be metric module (or MOD). If you can measure the outer diameter and tooth thickness accurately you should be able to work out what specification yours is.
But, as @Brun says, getting a 3D printed part in an appropriate material will be the hard part. You could use a 3D sintering process to make a metal part. No idea how much that might cost, mind.

Forum approved? Dunno. But I’m very happy with my Panasonic Eneloops.

Mudguard mount? What bike?

Not my track, but it’s this route: https://ridewithgps.com/routes/4620132

Ha! I think I got cramp and nearly crashed into the bridge parapet half way down.
The descent into Dinas Mawddwy on Sunday morning was fun too.

Careful, the route has changed. New one is tougher in some places, easier in others. I rode the ‘Classic’ route a couple of times on fixed. Like @Greenbank I was on 67” or so and nothing was terribly hard except the climb to the YH second time around.

2008, I reckon.

Don’t know about the price.
Have been slowly sorting the lathe out and getting some practice in over the past few months. Dirty side of the garage now looks like this
Grinder and belt sander, pillar drill and lathe with new tool storage for cutting tools and accessories.
Fitted a DRO, task lighting and some storage for toolholders, lubricants and other useful stuff
Got a 3D printer and a bunch of hand tools to play with
Want a mill but can't afford one (yet) so I got a milling slide and machine vice for the lathe. This, along with a collet chuck and some milling cutters will let me get on with some of the more complicated bits for the frame jig build. Made the adaptor plate (the blue thing) from a piece of O1 tool steel.
Also made a start on some tube blocks. Totally not worth the time taken to make them, but satisfying to be able to do it all myself.
