Here is my 2019 Christmas Ornament. I design one each year that I can customize with each family members name (look at my previous posts for examples).

This year I designed a two part print in place tree ornament where the center of the tree prints with an integrated swivel axis. Once printed pop off the bed and the center can revolve inside the outer tree profile. I print the center of the tree with zero top and bottom layers and a honeycomb infill. This makes the names which are cut out as a stencil pattern appear to be floating in the honeycomb.

I designed this in solidworks, and have included the native solidworks file. Also included are an STL without the name cutout (you can use your slicer or a cad package like Fusion, Onshape, Solidworks, TinkerCAD, etc to generate the name cut). And I have included a fusion360 and Step file for you to import. Feel free to modify, reshare, customize to your hearts content. I included my PrusaSlicer 2.1.0 Project file as a *.3mf file (from back in 2019).

Materials and methods:

I printed my part on a modified Ender3 printer. Printed in PLA, 3 perimeters, 0.2mm layers, 30% honeycomb infill.
