I recently watched a video by The Hacksmith where he 3D printed a gun to hold roman candles. A lot of fireworks are illegal in my state so I usually have to settle for sparklers, giving me the idea to make a sword hilt to hold them. Similar to the Hacksmith's design, one simply inserts the sparklers into holes on the piece and can take them out after use.

Step 1: Parts

What you'll need:

-5 Sparklers (can be modified to hold more or less)
-1 inch diameter pipe (again the design can be changed so you can use other sizes)
-3D printed part (can be found on https://www.tinkercad.com/things/a340xwERiXN-sparkler-sword-handle)

Optional:

-Zip ties
-Hot glue gun

Step 2: Assembly (Part 1)

The bottom of the 3D printed part will allow you to securely fit the pipe inside. I added hot glue afterwards to ensure that it wouldn't slide off.

Step 3: Assembly (Part 2)

The holes on top are for the sparklers to fit in. I accidentally made the holes to big and had to hot glue the sparklers in place, so it would be preferable if you can make adjustments to the part. I then zip tied the sparklers together to keep them close and in more of a blade shape.
