Make your own slide-on macro lens for the iPhone 4 or 4S. I designed this for my iPhone 4 when I couldn't find the image quality I wanted for less than $60.

Print this model and then buy the glass lens for $4 from Surplus Shed (http://www.surplusshed.com/). The Surplus Shed part number is L4471. For some reason the search box on the Surplus Shed home page does not work with part numbers. To get to L4471, use the "Lens Finder". In the Lens Finder type:

Lens Type: PCX, Plano Convex
Diameter: 12mm to 12mm
Focal length: 51mm to 51mm

It will get you to L4471

The lens fits in a recess in the model and is held in place with a few tiny drops of Superglue. If you get any glue on the lens it can cleaned off with nail polish remover or acetone. The lens is plano-convex (one side is flat). When inserted in the holder, the flat side of the lens faces the phone.

Note that the lens fits pretty snugly into the opening. Try fitting the lens before applying any glue. A good technique is, with the lens holder laying face-down on a table, lay the lens in position, and then push it into the recess by poking the lens with the eraser-end of a pencil. Once you know the lens fits cleanly, push it back out and put two tiny drops of superglue on opposite edges of the opening. I use a toothpick to apply the glue because squeezing the superglue directly out of the tube risks putting on too much. Then push the lens back in the same way as in the test fit.

The object pictures in the photo gallery (dime, ruler, and watch) are unedited and uncropped shots directly from my iPhone4.

This model will not slide over iPhone cases.

Escher's Playground - Reminiscent of the upside-down staircase paintings by Escher, this 7x7x7 maze will soon have you forgetting which way is up and down. The dimensions of this maze are 40mm by 40mm by 40mm and the ball is 9mm in diameter.

Ethereal Maze Puzzles are mazes that you solve by rolling a ball through an innovative new three dimensional lattice structure which forms the maze paths. The goal is to roll the ball through the Labyrinth Maze from the entrance to the exit. An additional challenge is to navigate the ball from the exit back to the entrance.

Start by pushing the ball into the spring loaded entrance ( it looks like a backwards “J”). Tip the maze in different directions to roll the ball along the paths through the maze. Don’t worry, if you make a wrong turn, the ball will not fall out of the maze. If the ball runs into a dead-end you can just roll the ball back the opposite way and try another path, that’s all part of this fun brain game. When you reach the exit there is a spring loaded button to press to release the ball from the maze. The exit is in a corner of the 3D maze, where you will find a bar with the little button sticking out from the side of the maze.

Each maze game come with the ball attached by a little chain link cage for shipping. This needs to be cut off and cut open with scissors and the ball will fall out. Note that each larger size maze comes with a larger ball. The balls can quickly and easily be colored with a highlighter or marker. Let the ball dry for a minute after applying then roll between clean white paper to remove excess color so it does not rub off on the maze. Paint for plastic models can also be used. The orange, green and black balls in the pictures were colored with highlighters or markers. Coloring the ball makes it easier to track in the Labyrinth maze.

See for yourself how Ethereal Maze Puzzles take maze puzzles to a whole new level of challenge and fun. With their convoluted lattice structure they can also be enjoyed as captivating and intriguing sculptural works of art.
