Quiver Cap for Easton Flipside Quiver

This model is inspired by numerous similar models, none of which quite fit the geometry of my quiver and accommodate my 27/64 arrows.  The cap is essentially a cylinder (OD 31.25mm) with a shelled cap (OD 40mm) to lip over the top. The holes are ellipses (16X13mm) which keep the arrows/fletching nicely separated but allow for some give if I bump into something.  Printing this in TPU with fuzzy skin gave it a nice grippy texture and it stays in nicely.

This is literally my first design ever so I'm sure improvements can be made.
