I needed a triple Honeycomb insert with an M4 version for a project I was working on and couldn't find one so I quickly whipped this up in Tinkercad, thought I'd upload it as others might find it useful.
Edit: Wound up needing an M3 so I've added that as well.
The author remixed this model.
Combined a insert-hollow-tre.stl and insert M4.stl to better suit my needs.
