Place it on top of the cage where it drips down as many leaves/plants as possible. Do you have an exotics/reptile store near you? They usually have a bigger variety of feeders that you can get ASAP. There are lots of reputable online feeder stores, too, for an even bigger variety
I don’t think there is one near me but I can ask around and find out. I’ll post a picture of my cage in a few. Idk how I can get my dripper to be at the top with such a short tube going to the motor. It’s a dripper that looks like a leaf, with a motor to sit in a bowl of water to pump it through a small tube.
Here’s my tank
I have posted my enclosure
Here is my dripper
Here is my cage and lights. Left light is natural light with no UVB, right light is 10% UVB.
I don’t think he will make it to Monday, regardless of what I do at this point, unless someone thinks it’s still possible to revive him. Half his body is gray / black, and half is very light grey, resting on floor of cage.
I do appreciate all the suggestions to help care for my chameleon. Thank you all for responding so quickly, I did not expect a response until probably a few days or a week after I posted. I will write these tips down for when I get another chameleon one day.
can you not take him back to the vet and explain that their treatment isnt working? At this point the kindest thing is most likely euthanasia as you don't want him in pain, you should be able to get an emergency appointment if you explain that he's turning black/grey. Doesnt sound like he has long left but it can take days for them to pass sometimes and you want to do what's in the interest of the cham.
With him turning black and grey and laying on the bottom of his enclosure, I agree that it may be best at this point to take him to a vet to end his suffering. Unfortunately, chameleons seldom show signs that anything is wrong until it’s too late to help them. If you aren’t able to find a vet that is open, just place something soft beneath him and let him pass peacefully. 
. You should probably concider calling the vet & talk about other options. 
I’m 90% sure my veiled chameleon has passed now unfortunately, as it’s laying on its side, not moving or reacting when I move / touch him and is gray all over. Vet called and said they suggest getting a chameleon from a breeder rather than a pet store. Anyone suggest any chameleons for beginners? One that would change color would be cool, like a Panther Chameleon I think they are called? But if it’s a lot more work / challenging to take care of that may not be good then to start.
I have, they said they need poop samples to test for parasites. He was too small and skinny to really do anything else they claim
So it is not that one is easier than another. They all have very specific husbandry that is required for them to live long lives. I have a petco Veiled, he is now three and a half years old. But he has had the correct husbandry from practically the first 2 weeks after having him.
Again, I’m very sorry.
I'm sorry for your loss, it's always hard losing them. Although if they thought he was really that bad and couldn't be treated they really should have euthanised him rather than sending home to suffer (that's on them, not you, i just think their decision not to offer that to you was very unethical considering the state he was in) because it's more humane. I agree about going to a breeder not a pet shop but once you've got it its all about the care. Out of curiosity how long did you wait before taking him to the vet and did he lose all the weight over that time or did he lose it in a short period of time? Even with parasites I think it would take a while to get this bad and would have been progressing quite slowly, were the vets just really booked up and not able to see him until it was too late?
This all happened in a course of 2 weeks. Noticed slight weight loss 2 weeks ago, waited 4 days to see if it got worse or better then called vet for emergency visit, they gave me medicine and that was that. He seemed fine and normal before that.
