Crenellated2

This is the third of 3 parts made from the same basic geometry. The other 2 are https://www.thingiverse.com/thing:3309551 and https://www.thingiverse.com/thing:3321322. All 3 are shown in the second image above.

This part has exactly the same geometry as Crenellated3, but the method for creating the Loft shape uses the "Tight" parameter instead of the more normal one that produces smooth curves. This simple change easily produces fairly dramatic results, which is why I chose to use design sof
