Heres a picture of mine. Yes it is not the most prettiest but i was only aiming for it to function as a dripper. Im sure it can be modified to look prettier. It works for me and is fairly easy to do, the air flow tips cost me $5 at the petstore and i got them in a pack so there alot of them if you want to make multiple. the tubing i already had from previous aquariums but im sure you can get a nice amount of tubing for a good price

or if you want to hang it in the enclosure just make holes on the top and put some string or wire and attach the tubing to the bottom and boom you have a hanging dripper
