Christmas Tree Star

Specifications

These are the dimensions of the completed star:

• ~ 225mm (8.85 inches) wide
• ~ 265mm (10.25 inches) high
• ~ 75mm (3 inches) thick

Creating the Parts

You'll need to print the following quantities of the parts to create the complete star: 

3x Star - Point

2x Star - Point - Notched

2x Star - Interior Structure

1x Star - Bottom Shroud

I printed mine with a 0.4mm nozzle at a 0.2mm layer height. Points were printed with 0% infill, while the other parts used the standard 15%. Other Prusa Slicer settings were left on default. 

The optimal print orientation for the interior structures and bottom shroud are fairly straightforward, but you'll want to print the points “point up” with supports. See the image below:

The filament I used was Eryone Silk PLA in silver.

Assembly

You can glue the parts together if you like, but they should be able to hold together with friction alone. 

Once you have all the parts printed, start by aligning the two interior structures:

Then insert the star points over the interior structure:

Note that the two notched points are slightly different, the notch allows them to fit around the shaft in the bottom of the interior structure. A normal point is shown on the left, while the notched version is shown on the right: 

Once you have all the points inserted, you should be left with this:

Then insert the shroud over the shaft on the bottom of the star:

Now your star is complete!
