A local printer from 3dhubs was able to help me print. It wasn't cheap, but this is a niche market still. ~$50 when all was said and done.

200 layer height PETG material. Seems sturdy enough for my application.

When printed out, the earlier-attached schematics fit a 1.5" PVC tee pipe perfectly. Thanks again for the recommendation to 3dhubs ServiceXp.
