Air Layering frame made of interlocking circular forms. The design is based on work from Pmoews "Spherical Cat Toys" OpenSCAD design. Thanks to his help in figuring out how to modify the design to accomodate the features needed. The design is customizable for both the overall radius, and the hole size for the tree or limb you want to airlayer. The design uses little material and prints without support.

The design produces one half of the full sphere, so you'll need to print two for a complete Air Layer Frame. I have provided slits for tie-raps or clips (I'll add that design to the post later), to hold the two halves together during installation. Simply fill the sphere with wet moss, place it around the tree, and secure in place.

The posted example file has a radius of 45mm, with a 12mm hole size. You can customize this to fit as tightly or as loose as you want around the tree. The grid holes allow you to see when the roots have grown sufficiently for removal. The frame is strong enough that it can be left on after the limb is removed from the tree, without disturbing the roots, giving the new tree time to gain strength before removal.
