I have orderd on amazon a set of Darts for my electronic dart board:

As the tips and additional parts didn't come in a handy storage box, I designed this one to store the Tips (I have 2 compartments because I have replacement tips from the board itself), Flights, 6 shafts,  Tool and a smaller flatter compartment for small stuff like rings and stuff.

I printed it in PETG on my Mini+ (with new firmware) and it worked out fine.

I hope it is of any use for some of you.
