Metaball Skinner earns its place in the superhive library for a focused job: turning wireframe skeletons into manifold, printable meshes where Blender's skin and wireframe modifiers fall short. It's a Blender Dev Fund contribution with 100+ recorded sales.
Metaball Skinner solidifies wireframe and skeleton meshes in Blender, designed specifically for 3D printing. It places metaball rods along each segment of the skeleton so a manifold mesh always forms, no matter how complex the geometry. That makes it especially advantageous for highly complex branching or latticed geometry, such as 3D models of networks like neurons, trees, and social networks.
Blender already offers the skin and wireframe modifiers to thicken a wireframe. The skin modifier can produce creased, self-intersecting meshes when the angle between edges is too small or a tiny edge stems from a larger one. The wireframe modifier only works on meshes that have faces, so it will not function on a mesh skeleton representing a tree. Metaball Skinner instead produces readily 3D printable models for any mesh, regardless of geometry.
The metaball object tracks the location, rotation, and scale of the base mesh using constraints, and half-resolution update is set as the default, better suited to large mesh-skeletons. Documentation is included, and the add-on is distributed under the GPL license.
Metaball Skinner is best for preparing complex branching or latticed wireframe and skeleton meshes for 3D printing in Blender.
Metaball Skinner is completely free to download and use.
Metaball Skinner lists compatibility with Blender 2.6x, 2.7x, and 2.83, and version 1.2.0 was updated to work with Blender 2.83.4. If you are on one of these releases, the add-on should install and run as described. For newer Blender versions, the developer's page is the best place to confirm current compatibility before you rely on it for a print job, since these are the versions stated for this release rather than a guarantee of anything later.
Metaball Skinner produces readily 3D printable models for any mesh regardless of geometry, which the built-in modifiers do not guarantee. The skin modifier can create creased, self-intersecting meshes when the angle between edges is too small or a tiny edge stems from a larger one. The wireframe modifier only works on meshes that have faces, so it cannot process a mesh skeleton representing a tree. By placing metaball rods along each skeleton segment, this add-on always forms a manifold mesh instead.
Metaball Skinner is listed as free in this catalog and is distributed under the GPL license. Licensing and terms can change over time, so check the developer's page for the latest details before you download. The add-on ships with documentation to help you get set up, and it thickens wireframe and skeleton meshes for 3D printing across the Blender versions it lists. It has also recorded 100+ sales as a Blender Dev Fund contribution.
Metaball Skinner sets the metaball object to track the location, rotation, and scale of the base mesh using constraints. This solves the earlier behaviour where the metaball object appeared at the origin even when the base mesh was positioned somewhere else. The add-on also sets half-resolution update as the default, which is better suited to large mesh-skeletons. Together these keep the generated mesh positioned with your source geometry while remaining workable when the skeleton is large.
