ok so my halfling arrived last week and i'm kinda annoyed because i can't figure out how this thing is supposed to come together. maybe i'm over(or under)thinking this but when i push the carto tube all the way in there's no room to insert the drip tip. so when i push the drip tip in the carto tube is pushed out about a third of the way. that can't be right either. it'd be nice if these things came already assembled for maroons like me. kinda frustrating. any ideas? cuz it'd be nice to actually use this dagnabbit contraption.
