Allon designed and simulated a Muenster Brace custom fit to a 3D model of a human arm using Autodesk Fusion 360 with design objectives for it to be "less-medical" in appearance, lightweight, strong, comfortable, and 3D printable. ABS plastic is the intended material for printing because it is stronger than PLA. As such, ABS is the specified material for the static/force simulation.

The static force/load simulation proved the model successful as the maximum simulated deflection was within 2 mm without straps both for attempted supination as well as pronation. The stresses were determined to result in a minimum safety factor of around 5 for both as well. Straps were shown to cut the displacement by a factor of 5 and more than double the minimum safety factor. Real world testing is needed to identify simulation shortcomings and to test the fit and comfortbility as well. Allon has reached out to a daily Muenster Brace user to see if they are interested in testing/using this model.
