This is my entry for the Make-Ultimaker Contest. It’s a one-piece print with 18 hinges and a screw mechanism to control the opening of the ornament. There are some cool techniques in this model that I would like to show in detail. I named them: SmartBridge and StencilWall
The egg is a one-piece print with 18 hinges and a screw mechanism to control the opening of the ornament. There are some cool techniques in this model that I would like to show you in detail.
The usage is very simple: Print the egg in one piece, grab a coin and open the egg gently. The first time you open the egg there are 18 SmartBridges that will break (it makes a pretty cool sound, if I say so myself). Then you need to screw your coin clockwise to open it.
The first time it will be a bit rough (don’t worry, it won’t break), but after once having been opened and closed, it will open and close easily.
Print Instructions:
This model is printed on a Replicator 2 with standard settings.
LayerHeight: 0.2mm.
No Raft - No Support.
If you use another slicer then you need to make sure that the bottom layer is at 100% or less.
SmartBridge:
I haven’t seen this technique before, that’s why I named it so - hopefully Iam the first one :-). The concept is very simple. To create a horizontal one-piece hinge, I’ve added a small bridge of about 0.4mm right beneath the hinge. Once the hinge is getting moved, the support bridge breaks and the hinge is free to move.

StencilWall
A stencilWall is a simple way to add some color to your print. It’s a tight layer around your models with some shape in it. This way it can be sprayed easily. I also created a seam in the wall for easy removal.
