This is a Halloween themed Wreath or table decoration with a dead crooked branch appearance. It is printable without supports and assembles without glue. The main branch fills most of one Bambu plate and the smaller three branches fit across two plates. It takes only a few hours in total to print all the parts. The completed size is ~ 35 x 30 x 8cm (14 x 12 x 3 inches).

An addon spider ornament is now available here.

The assembled model can be further bedazzled using any props at hand - I had some spiderweb and small LEDs from a local variety store. In addition there are three small unused mount holes on the main branch for potential future addons. The light weight nature of the printed part means it can be mounted in a variety of ways - string, hook , 3M strips or, as shown here, a small strip of Blu Tack.

I designed the parts in Blender. Firstly I merged all vertices on the template cube to the origin, creating a single vertex. Using the Extrude function I generated the main branching wireframe form and added a Skin modifier to build the branch radius. On top of this I added a Deform modifier referencing the basic Blender “cloud” texture to give the skin some random irregularity and make it look a bit more “tree” like. Given the scale, the 3D printed layers actually add some nice texture in and of themselves. A large cube was used as an object for a difference Boolean modifier to slice the parts in half before they were exported as STLs for printing.

I printed all the parts using Bambu PLA-CF - I think the carbon fiber adds a great look and feel to the finished model.

Instructions:

1. The .3mf files are attached but if printing from the STL files, note that one of the three copies of the branch (to go on the left side) should be mirrored in Bambu Studio. I used the default 0.24mm setting for the main branch and 0.20mm for the smaller branches to maintain some degree of detail on the tiny ends.
2. Once printed, insert the branches into the three larger holes on the main branch (they are designed to fit snuggly and should not fall out).
