Halloween // Need some help with ideas for accessories for a Wizard costume

Going with a very simple wizard costume this year, but I'd like ideas for some small magical accessories.

I've considered getting some flash paper or one of those wands that launch flash paper.

A small smoke machine (basically a modified vape), could perhaps be used for some magic effect. Idk what exactly though. 🤷

I need more ideas! I have access to a 3D printer as well so I can manufacture a bit of stuff if needed.
