Bagel slicer with crumb tray

I modified the solid model of the Safe-T-Bagel with a tray at the bottom to catch the crumbs. It is fairly large (mine used 264 grams of PLA). I think it could be scaled down slightly (maybe 90%) or shortened and still be useful, unless you have huge bagels to cut.

I found that sawing bagels with a large serrated knife did not work as well as a long straight knife. Put the knife into the slot and push down on both ends evenly.
