I ran across an online post that misspelled the word “angels”, and it got me thinking – why not make a set of actual “Christmas Angles.” So here they are, 8 Christmas Angle tree ornaments, marked in degrees and radians. Good for kids who are learning angles. The halos serve as attachment points for standard wire ornament hooks.

The highlights shown in colors in the photos are raised above the rest of the ornament. I used this to print a different color for just those highest layers. But the raised areas are somewhat visible even on a monochrome print, and could also be easily highlighted with a marker or paint.

I used a Bambu X1C that can swap colors during the print. Since there is only one color swap, it doesn’t create a lot of back-and-forth purging waste.

The storage box has cavities for storing the hooks, as shown in the photos.

This .3mf file uses PLA Silk for the box. To get the sides smooth I had to make the sides solid and use low speed. This would not be needed for other filaments. Also, there are some tricks in setting it up so that the head movement is continuous on the last layer before the embossed letters. Again, this would not matter for filaments other than PLA Silk (which shows any discontinuous movement as a scar).

See the head movement in the “Preview” tab in the .3mf file – it is one continuous zigzag on the layer before the letters. The tricks to accomplish this include:

(1) I redesigned the model so that everything was exactly an integer number of layers (in this case, 0.2mm). That way, the transition from flat surface to embossed letter occurs at a layer break.

(2) I changed the upper 3 layers of the top surface to be their own body (in fusion 360 you can export .3mf, then import geometries to Bambu Studio, and the shape will consist of multiple bodies).

(3) I changed the profile for the top-surface body to have more than 3 solid BOTTOM layers. That way, when the slicer gets to the top flat surface, it still thinks it is printing “solid infill”, and not a top layer. See slicer view colored by line type. That way it doesn’t “look ahead” and see the letters and freak out.

(4) For reasons unknown to me, this only worked when I set that section to 1 Wall instead of 2 Walls.
