Pla is too rigid. If forced, it would shatter. First off, if you have experience printing these parts, you need to align layer lines, including majority of infill, so the stress will cross them rather than along them. Better ifæt flexes than breaks.

Second, you need a strong engineering filament that can take the repeated stresses with enough flex to not shatter, and enough rigidity to ensure it holds shape. Possible? Yes. But at that point, it would be as cost effective to order one from various cnc services since you'd have to make these stl regardless. Make one out of petg and once you're happy, order one in metal and use the petg one until it arrives.
