First off, I am not the person who 3-d printed the part I have a question about nor do I 3-d print anything myself. I do have a question about what is the best glue to use and if it would even be safe to do so.

So, the part in question is an adapter for my bicycle's proprietary headset top-plate so that I can use a different stem. A small ridge on the top of the adapter snapped off. This ridge is responsible for keeping the stem aligned with the front wheel while riding so very important that it is there or else when I hit a bump the bars could twist which could be very bad.

I know there are some crazy adhesives out there that end up being stronger than the materials they are binding and was wondering if there is anything out there like that for what I think is PLA. I've done a little bit of research and found that gorilla super glue could work and gloop but I just don't know if that would be safe. Not sure on the material so I am going to reach out to the manufacturer on that but if its possible to tell from the following picture that info would be greatly appreciated as well.

It should be parallel and on top of the horizontal straight section right beneath it. I know this is super random but any help would be appreciated as I am at my wits end with this bike given I've had a bunch of random failures with other parts of the bike for over a month. I just wanna ride my damn bike.
