The radius of collagen fibrils vary widely depending on experimental conditions \\textit{in vitro} or anatomical location \\textit{in vivo}. Here we explore the variety of thermodynamically stable fibril configurations that are available. We use a liquid crystal model of radial collagen fibril structure with a double-twist director field. Using a numerical relaxation method we show that two dimensionless parameters, the ratio of saddle-splay to twist elastic constants $ k_{24}/K_{","authors_text":"Andrew D.
