Gell Gun Hopper

This adapter threads a bottle onto the Picatinny rails of a gell shooter with a hole to funnel the balls into the gun.

I printed mine @ 0.2mm with tree support for the center, 4 perimeters, and 40% infill.
it fits super tight (a good thing). the bottle threads should be face up when printing. I also used " Ultimaker Cura Arachne_engine_beta_2 99.10.0 "
My Ender 3 takes 2 hours at stock speeds.

I tried AntomanElvens design but it didn't work properly for these guns

I made this design from a cad drawing of the Picatinny rail standard and scaled it to fit the gun then imported a plastic bottle cap from McMaster car and scaled it till it fit well.
