When my son received his Gel Blaster surge for Christmas and tried it out immediately after opening presents with his sister you can imagine the disappointment when the hopper broke. The hopper is made of lighter material than the feedneck.

As such I created this using the starting hollow grenade below and tweaked the screw on a few times to get it right. Printed this with a clear PETG so you can see the colored gellets and it is much heavier duty than the original hopper....

Enjoy!
