Reddit had a community called something like 3dprintmything where you could post what you were looking for and get bids from folks who could get it to you. I dunno if we have anything like that here.

Local libraries often have 3D printers now a days

Check your local library.

Stratasys, Protolabs, Shapeways, Hubs, etc. Tons of options out there. Search 3D printing and your closest city and I'm sure there will be something.

JLCPCB has a 3d printing service

I had this exact question last week. Found a UK based hub service with providers in many countries. Search for Treatstock and see if you find it useful.

Ps. I'm not affiliated, not an ad bot, etc.

Of you have a model file there's services online, someone else jlpcb and I'm pretty sure shape ways is still a thing. You usually can fine printing services on eBay too.
