I love BaudlerArtDesign's remix of drawers to fit Hatchbox spools, but that design left a 3.5 mm gap between the walls of my Hatchbox spools. I remixed the drawer to make it 3mm taller, and now they fit much better.
This is only the altered drawer. BaudlerArtDesign provides a number of other useful parts that go along with this, as well as assembly instructions, so be sure to check them out.
Update: This stl has some mesh issues. It works fine using Slic3r, but other slicers may or may not enjoy it. I'm working on a fix -- but I'm new to this, so be patient.
Update Update: This new mesh should work much better.
