The idea for this project was to create a light switch cover that creates the illusion that there is a monster living in the walls.
This was my second attempt at using Blender for 3D modeling, and I wanted to experiment with the sculpting tools. The approach was to just keep experimenting and using the different brushes until I was happy with the resulting face. Once this was complete I imported the Rounded Lightswitch cover design and cut away a portion to expose the sculpted face. Steps were then taken to reduce the complexity of the face (specificaly for portions not visible after printing) and to make sure there was room for the light switch to still work.
A good learning experience, and I'm happy with the final product, but the design approach could have been better. If I were to redesign I would make more manual coarse adjustments to get the general shape of the face before using the sculpting tool.
This is based on a scene from the Attack on Titan manga (see reference_images/wall_titan_manga.png)
The original light switch cover model was pulled from http://www.thingiverse.com/thing:53554 (Rounded Lightswitch Cover by zthralls)
The reference image from from a Google image search for "wall titan" or something similar. I cannot find the exact source where this image came from but my guess is http://attackontitan.wikia.com/ or something similar. The scene is from Chapter 33 Wall I believe.
Reference image was added so that it was visible when front view was selected. Added rounded lightswitch cover and cut hole for titan face to show through. Titan face was created by using scuplting tool with dynamic face division to ideally add detail where needed. Not extremely pleased with this option as it created a lot of (probably) unnecessary vertices.
WallTitanSculpt.blend was modified to be 3D printer ready. This consisted of closing up titan face and reduce as many non-visible faces to make printing move quicker. This was done in an extremely manual process, hence why this was moved to a different file. Again, probably could have done better here to not using scupling tool with dynamic face division so much...
This was modeled in Blender 2.75a.
A MakerBot Replicator 2 was used to produce physical light switch cover. Settings were for highest quality and smallest possible layer height. Do not remember other details, other than print time took roughly 8 hours.
