A simple slide-together two-piece breadbox with a nested slicing guide. Had some minor adhesion issues that didn't affect the interior at all, so I just ignored them. This was an insane print that took about 10 days to print and used 1.6 kilos of Tough PLA. Cost-wise, this was nuts, and I doubt I'd do it again. But I now have a sturdy breadbox sized to fit the 2lb loaves produced by my Zojirushi Home Bakery. :) The handle is optional, and I just glued it on with CA.
