Thanks for downloading!
We'd love to hear from you if the print was successful.
Makey Eggmass
Hi, fellow Makers. 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 ome cool techniques in this model that I would like to show in detail. I named them: SmartBridge and StencilWall

Description
Last Updated 2015-12-15
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 afteronce 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 I
am 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.
See images for more detail.

I would like to thank:
Makezine: For making this contest happen, of course.
Ultimaker: For support.
3DHubs for connecting designers and 3d printers.
JATMN ,Sybren_Zwetsloo, 3Dvangelist for test-printing my design and providing the necessary feedback to make the model usefull on different printers
3Dvangelist tested the print on a Da Vinci PRO
LayerHeight: 0.2mm.
No Raft - No Support.
JATMN tested the print on a Wanhao Duplicator 4 using Simplify3D
LayerHeight: 0.2mm.
Infill: 20%
No Raft - No Support.
Sybren_Zwetsloo tested the print on a ultimaker 2
LayerHeight: 0.2mm.
Infill: 20%
No Raft - No Support.
ProTip:
Since the design is egg-shaped, you can also use it for next Easter
(saves you material and time).
Materials and methods
It’s Just a one-piece print.
In the download section you can find the source files (it's designed with Autodesk Inventor 2013).
There is a print-ready stl file and there is also a print-ready stl version with StencilWall.

Lyssens Yves commented agoHi Ruggb,
I did't try the model to slice with Slic3r. And I have actually no experience with that slicer.
IAt Layer 73 there are 6 smal connections with the center stem. Just enough to carry the weight of the moving part. Once printed, and opening, these 6 small bridges will break so the movement fits in place. It probably think its not manyfold caus the slicer doesn't see the bridges as a true connection.
I know its a hard print, but in my oppinion that what it also make it special.
Hope you still want to try to print this and keep us updated on the result.
Best Yves
Bill commented agoLook great - neat technology. I have a home built coreXY printer using Repetier and Slic3r.
Slic3r thinks the model isn't manifold, but will slice it. Viewing the model, layer 75 shows a circle around the center stem hanging in mid air. It looks like it eventually connects to the center stem, but it sure won't print that way.
Why does Slic3r think it is not manifold? Did Slic3r break this? How will I get it to print?

Thanks for the nice compliment.
I am very happy with the winning;
Looking forward to start exprimenting with the ultimaker
Erik de Bruijn commented agoImpressive design! Congratulations on winning. It's well deserved! The Ultimaker and YouMagine teams are looking forward to seeing what you'll design next.
C. Michael Neely commented agoCongrats Lyssens! Enjoy the Ultimaker2!! Happy Holidays and Happy New Year as well. Cheers!

Thanks for printing.
Going to see if I can make it stronger.
There is not much place left inside the egg.
merry xmas and happy printing !
JAT.MN printed this ago
- Printed on:
- Wanhao Duplicator4X
- Result:
- Printer was actually a Duplicator 4 not X.. But anyhow. Looks cool, some stringing and broke in 2 places but I blame my printer for that issue.
- Feedback:
- Very cool, might need to make some of the connecting areas of the hinges a little stronger..
