This is a modular bauble ornament allowing you to make a variety of different ornaments from the same collection of pieces.
By varying the colors and choosing which add-ons to stick onto the ball you can create many different baubles that can hang on a tree.
This print was made on a MakerBot Replicator 2.
I scaled every piece by 120% but you can go higher.
Try to print the add-ons and pegs at the highest resolution.
The ball, top and bottom work well at 0.15 mm.
There is a snap-fit peg used for connecting the top and bottom to the ball.
The snowflakes have their "snug-fit" pegs built in but the other add-ins have separate pegs to push in. You may have to do a bit of sanding on the pegs if they are too tight.
