But the common method of connecting it into a loop and letting the belt dangle freely while firing can be abit too obstructive and looks messy, especially when playing fast paced skirmish games that involve quick fire and movement.
Therefore, i created a custom Ammo Belt Drum for the Belt Blaster, something to keep the ammo belt secured in a container yet allowing it to cycle freely (and still look cool at the same time!).
Here is how i made my custom Ammo Belt Drum:
Step 1: Get a CD Spindle Case (8cm tall) and Velcro Strips with adhesive backings.

Step 2: Cut a hatch into the CD spindle case cover, the hatch width should ideally be 4-5 cm wide. Make sure the right side of the hatch (shown in the photo below) is left attached to the cover, this will be the hatch ramp. Also cut out the CD spindle.

Step 3: Position the ammo belt in the drum (as shown below).
It should look like this.

Step 4: Stick the Velcro Strips to the Belt Blaster and Ammo Belt Drum.

Step 5: Attach the Ammo Belt Drum to the Belt Blaster.
Note how i wrapped the Ammo Belt over the top of the Belt Blaster's belt rotator cover.

Final Step: Locked n' loaded... Ready to deploy!
