Baddone, nicely done.
I had the Loobman but the parts that rubbed against the sprockets only lasted so long. Then I set it up just over the chain so it would do a slow drip because I added some foam inside the plastic line, but that got messy.
My latest solution that has worked for a long time is two foam paint brushes sandwiching the plastic line, so when I squeeze the bottle, the lubricant goes down the line and soaks the foam brushes, the foam brushes rub against the entire top of the chain. I give it a squeeze just before riding at times or during riding. My chain is always sparkling clean now since it constantly rubs against the WD-40 soaked foam and stays well lubed.
