I’ve used a few different types - I usually go with a clear UV-curable adhesive or resin, so that the component is visible after curing. The one I’ve got on hand now is Dymax 9-20557, since it was available from a local distributor and got here fast. I’ve also used the Formlabs clear resin on occasion, or a two-part epoxy like the JB weld clear-weld or Loctite plastic bonder. Pretty much as long as it cures hard, and is viscous enough to apply without spreading everywhere, you should have good results.
Hope that helps, let me know if you have any questions.
