Will standard stationary glue work (Elmer's, Kokuyo, or similar), or does something stronger need to be use? Additionally, I also need to glue in magnets into my 3D prints. What is the best kind of glue for this use case, or will any do fine?

They will only be used for a few prints, so I would like to avoid very large containers. Small bottles and syringes are ideal

edit: I will probably go with cyanoacrylate (CA) glue then. 3D Gloop has also been recommended, but is not sold by any local retailers and international shipping will take too long for the project I need to use it for. Could be a neat option for some people though. Thanks, everyone!

Somebody has also suggested acrylic/plastic cement for chemically joining plastic parts together, but in my experience with laser cut acrylic, it's difficult to apply and can also affect the appearance of the print if you mess up. It also has a very short time window between application and fusing. I'm sure it works fine, and it will probably hold up better due to the plastics being chemically fused, but I will go with CA glue.
