The handles for my keezer / kegerator are made from White Labs yeast vials. The first step is to remove the label and adhesive from the vial. This was super-easy with the help of a cleaning product called Goo Gone. The adhesive is very difficult to remove from the vials (much more difficult than removing label adhesive from bottles). But with Goo Gone, it was easy. Then, see the pictures below on how to attach the vials to your taps.
A shout out to Matt Pieters and Tanu Happonen….the washer and bolt idea was completely theirs.
