Added some 45-degree angles to the set of dowel rod connectors by jeff_j3ffr3y. They are the same scale as the original set, which was intended for 3/8" dowel, but can be easily scaled to fit different sizes. I used a 45% scale for use with the approx 1/8" skewers that I had on hand.

DowelJoint225 is a solitary 22.5-degree angle.
