Large Hanging Monster Eye / Eyeball - Halloween Outdoor Decor

Update: I have changed the CC license of my models because of the lack of clarity around AI use. If you want to re-mix, reuse, rewhatever my model, just ask.. 
 

My new tree shed its leaves early so I was inspired to give it some Halloween love. 

These hanging eyeballs were designed to be a quick (relatively) print that was easy to assemble, dissemble, and store. 

Model Notes:

• The main full model file (all parts) illustrates how the final model can be assembled. 
• The print is as big as I could fit on my print bed. Roughly 17cm/6.5 inch diameter. However, it should scale down a bit just fine. I have printed it at 50% with no tolerance issues.
• I have included some ‘uncut’ parts:
  • The eyelids can be rotated and you can cut a hole in the slicer to adjust how wide you want the eye to be open. I recommend using the blender file for this. The blender file contains the ‘cutter’ object that I used to cut the holes. The file also still has the boolean modifier on the lids. You should be able to rotate the angle and export with modifiers to have the eyelids how you want. 
  • I chose a cat eye pupil for our print. However, the pupil can be re-cut, printed with a filament swap, or printed whole and painted. Up to you. For this I have included an uncut iris stl.
• I have included some alternate parts: 
  • Wide Lids: This is a basic ‘wider' open eye look. If you want the tree (or rafter, or whatever) to have a different look, but don't want to bother with cutting your own holes in the slicer, try these.  
  • Eye White with Rod Attached: This alternate eye ‘white’ has the pole integrated into the model. This was my first rendition of the model so I include it. It prints faster than the eye white and pole being printed separately. However, the pole being separate from the white makes it easier to store the prop and allows the color not to be white. 
  • Eye White Full Sphere: This is the full eye white with the back of the ‘white’ intact. If you want to exclude the lower lid or if you want a full round white, here you go. 
• They eyelids are designed so the prop wont hold water if it rains and hopefully, some of the water will be kept out anyway. 

Printing Notes:

• For speed, I printed mine with lightning supports. This worked well and kept the model light. 
• For my main full size print I printed at 0.2. 
• I have also done a print at 50% to test the fit tolerances. The resulting print is about the size of a softball. For the 50% scale all of the fit tolerances still worked great. For this smaller print I printed at a 0.1 layer height. 
• Some parts need support. My file is relatively minimal with supports. Your mileage may vary depending on your printer. 
• You could easily add a hole  by using a cylinder cut box in your slicer to make space for putting in an led. The center pole could hold the light puck in place. When printed with lightning supports, my yellow iris was very translucent. I may throw a light in mine for Halloween night. 

Assembly Notes: 

• All parts should be pretty obvious in how they can be assembled. See the ‘HangingEyeball_Complete.stl’ for a visual representation of how it all fits together. 
• There is room for rocks in the back if you need the eye to have more weight when you hang it.  

Enjoy!
