I have printed some connectors from PLA, in order to make a frame for a "tent" cover for my Ender3 printer
Since printing rods would be a long process with likely poor results, I'm using some cheap thin-walled metal tubes as the main structure, and printing the corners.
I plan on using 2 part epoxy to secure the metal rods into the sockets in my printed part, but can find no real chart of what glue to use with which FDM plastics.
Is 2 part epoxy a suitable adhesive for PLA and other hard items?
Confirmed - 2 part epoxy works fine between PLA and other things.
I used "selleys" brand, and found that the fastest-setting 5 minute version worked fine, but on paper produces a "weaker" bond than the slow-curing one.
The 5 minute version also has a distinct odour of cat pee, which is not present in the slow version.
Downside, the slow version took 2 days to harden completely, but my item is definitely secured together well.

NOTE that the above link says
Not suitable for bonding plastics such as Polypropylene and Polyethylene
