Description
Ultra Silly Shell except some varied internal sizing for performance since Ultra is stiffer and pickier. Available in .1mm-.25mm radial increases, so 16.2mm-16.5mm ID.
Any licenses, limitations, permissions granted by the original designer also apply to these files. Eg, if you have permission to sell prints from the og fileset, I extend it to cover my remix.
