Looking for guidance on purchasing a 3D printer for Acrylic or similar

[Econdron]

I apologize in advance, I'm very new to 3D printing. I'm looking for a 3D printer that can print a clear plastic/acrylic part. I attached a drawing of the part I'm looking for. Square tubing will fit over the smaller ends and it will act as a connector. The piece will be highly visible and decorative, so it needs to look like good. I don't mind flame polishing or acetone polishing the final pieces.

1) What machine do you recommend that could accomplish this?
2) What filament is closest to what I'm looking for? PMMA?
