The Compact Adapter Kit is a set of lightweight, compact adapters for neatly stacking different sized rocket parts. The models are well detailed and are themed to the style of the KW pack, and are 100% compatible with any parts that use any of the included standard sizes. Since the previous version that was on Kerbal Spaceport, I have re-compiled all of the models and added 0.5 > 1.25m and 3.75m > 5m sized adapters, as well as add values for career mode balance.
Included Sizes (in meters): 0.5 to 1.25, 1.25 to 2.5, 1.25 to 3.75, 2.5 to 3.75, and 3.75 to 5
