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.
See images for more detail.
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.

hi Sybren_Zwetsloo and jatmn, first of all thanks for testing the model. I’ve already modified the model, to prevent other users to have the same problems that you guys had. the turning point on the bottom has more tolerance than before. the first layer on a heated bed is slightly wider than on a printer without. I also added some strength to the joints. I did had the equipment to test it on other machines. so I’m very glad you guys did. The thing that its difficult to open the first time is very normal. the SmartBridges need to break first. This technique was the only way to get a one piece print. thanks again. Best Yves
Not sure why… but v2 came out significantly worse for me than v1 on my D4. nearly all of the petals were broken at the hinges before I even unscrewed it.
Course this printer isnt my good printer either…
