NY libraries have maker spaces. Not sure about other states.
The "kids" at our local version sometimes get a kick out of replicating stuff like that on the 3D scanner & printers. As has been mentioned, just choose a suitable polymer.
Also, be sure to choose suitably dense fill. Some machines default (or are set) to relatively low density to conserve material and save weight, which would be irrelevant for your app.
Local place charges by weight of material used at cost, and some ridiculously low hourly rate for machine time; depending on machines used.
I take in (donate) my scrap 1/8" & sometimes 1/4" birch ply, and scrap acrylic sheet plastic - they love the thin stuff for the laser cutters/engraver
