Ridiculously Small Christmas Balls 2025

Here's an collection of incredibly small Christmas balls. Great for mini trees, doll houses, train sets, and jewelry.

The secret to getting these to print well:

• Use the CLASSIC PERIMETER GENERATOR (In PrusaSlicer, it's under Print Settings -> Layers and Perimeters)
• Good cooling.
  Print at the lower temp range for your filament.
  In PrusaSlicer, go to Filaments -> Cooling and reduce "Slow Down If Your Print Time is Below" to 2 or 0. Default is 12. That may lead to the already printed layers not cooling properly and getting mushy.
• Good bed adhesion. I flattened the bottom of each ornament, but it's still a tiny area. I printed most of these with grid supports to keep them locked to the bed.
• Print with 1 perimeter
• The "super mini open spiral ribbon" prints best with organic supports for the roof.

 

I had a friend who kept printing my ornaments smaller and smaller. So, I modeled these so they could be printed smaller still. I've successfully printed all of them at 100% and most as small as 50%. They also look great enlarged. I've printed the double spiral ribbon ball at 270%, which makes it roughly 80mm wide, which is about the same size as my regular sized balls.

I started by designing my "super mini" ornaments. They are just under 30mm wide and I've printed most as small as 15mm wide. I wanted to go smaller, so I created the "absolute micro" ornaments that start at just under 20mm and I've printed smaller than 10mm.

At 50%, thread holes and loops tend to just disappear, so I've provided versions of each ball without holes or loops. If you want to add a hole, all you have to do is add a cylindrical shape modifier in your slicer the size and place you want the hole. Then set the properties of the modifier for top, bottom, infill and perimeters to zero. The same result as modeling a hole without any of the headaches. You could also just run a thread through the gaps in the ball (open spiral) or glue a string to the top. 

Since the absolute micro open spiral ball has lots of nice gaps between the arms, I ran a thread through them rather than modeling a hole or a loop for the ornament.

I print most of these with grid supports. It's really just to keep the ornaments adhered to the bed. The super mini open spiral ribbon needed organic supports for the roof to print really cleanly. Some need a little infill. They are all good with just 1 perimeter everywhere.
