A customizable comb which fits a Phillips Multigroom 3000 beard and hair trimmer.
In principle the design needs a cut between the top of the tines and the rear of the trimmer mount so that the spring clip at the back can flex, but in practice it seems to attach and detach nicely as it is.
Sand any hard corners off the bottom of the tines. These will be moving across your skin.
This design does have a number of overhangs, most obviously the trimmer base plate over the tines. So the tines have been positioned to be under all edges of the base plate. This makes it a bit blockier than the combs supplied with the trimmer, but it also means that the comb prints in one piece without significant problems.
Since the tines are important for supporting the upper part of the design, don't reduce their number (increase their spacing) too much.
