I found this transparent ring from a lamp and it flew quite well when I chucked it. I desgined a replica for y'all to pint yourselves. Print in material with decent toughness but I printed in PLA and it worked fine with me.
Be careful and don't throw it at people or indoors (it travels quickly and the edge can be sharp).
