Sometimes I use the ‘crumbs’ for a small print, like model bases or tests. Other times I weld all the remainder together and run it like normal. (This works for me because I tend to print in the same color and material alot.) My other option is using these small amounts for my 3D pen, which I use to join parts together like a welder. It works really well for some of the dice towers I print that come as two or three parts, on seams that won’t show. I super glue the last joint so everything is solid and seamless to the eye.
