I just got the Elgato Prompter* and wanted a quick way to seal the back when it's not mounted onto a camera. This quick print threads onto the 49mm step up ring that's included with the prompter, for the sake of minimizing printing, and because I figured most people won't actually need the 49mm ring (if you do let me know and I can adjust for some other size).
Default print settings. No supports required.
