I noticed that Lulzbot uses press fit nuts in it’s printer parts where bolts are screwed into the printed parts.

Does anyone know a part number for these? I’d like to re-print some of my parts for my mini.

They are heat inserts. Use can use a hot soldering iron to put them in. They can be found on McMaster-Carr, below is the link for the M5 version:
