Carbon fiber finishes look so good with 3D printed parts. Inspired by a Pringles tube, this safety extension/mini hopper was printed with PETG-CF and discourages/stops fingees from getting too close to where the fingees want to get (in this case, the hurty bits of the shredder).

I can also fill it with insufficiently-sized regrind to further reduce more of it into usable-sized regrind instead of doing a lot of little batches.
