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.

As seen on blog.objet.com, this is the updated model of the one shown in video. Now you can open the doors! This is the mid size model -- 2cm long. NO ASSEMBLY REQUIRED! You are getting one model per print/order. Let me know if anyone needs special text version. (thank you, happy birthday, etc) ** The older model, shown in video, is also available in my shop. **

This is the second and much improved version of my single-piece prybar and nail lifting tool with a range of metric hex drivers (5.5, 6, 7 and 8mm), a bottle opener, a 1/4" hex bit holder and two 1/4" hex driver points.
The centre cut-out will hold and store a standard PH2 or PZ2 25mm long quarter inch hex bit (not included).
Four o-rings are required to complete the assembly (10mm ID, 2.5mm diameter, not included)

This model is designed to be printed in Stainless Steel or one of it's variants.
I've been carrying this prybar around with my keys for a while now and it's functionality is just as i'd hoped with it not having let me down so far.
The prybar can be secured to a keychain or lanyard with a No.2 McGizmo clip or similar 25mm gate clip through the 5.5mm hex hole.

There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page.

This is matching pair of scales which will fit onto the sides of any 58mm model Swiss Army Knife with removable plastic sides, including the popular Classic SD. The scales pictured in the example photo are in Black Detail plastic on a Classic SD model SAK.

These are solid scales without slots for the tweezer or toothpick accessories. I have designed them to fit fully and snugly, so depending on the tolerances of the material you order them in, you may need to wrap the knife in a towel and carefully tap them on with a solid object until the scales are fully seated on the knife. Once attached to your knife I do not recommend removing the scales as the attachment holes may become damaged.

A small keychain survival whistle which emits a clear and sharp sound.
This whistle is of single-piece design and therefore does not need the small plastic insert which some other metal whistles require, that can work loose and fall out.

The attachment hole is 2mm wide and is perfect for a 10mm split ring (not included).
This whistle works very well in glossy silver.

There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page.

Metal cufflinks in the shape of the popular Fuchs wheels used by Porsche up to the late 80's for both 911 and 944 lines...
Also available in stainless steel and alumide. Stainless steel has a certain bronze tint, look at the photos from the wheel model to get an idea...

All items are made to order. This means there's a period of 2-3 weeks until delivery, depending on the material chosen.

Celtic cross, can be used as Keyring or for a nekclace.

It's a Spoon / Fork / Knife... All in one!

Inspection Plug removal tool complete with hexagon for key

I have been to the hardware store too many times, unable to verify the size of the nuts, bolts, washers, dowls, molding etc, so I desgned my own mini measuring tool that fits on my keychain. Others are usually too big or just inaccurate. Includes the following Measurements 1mm; 2mm; 2.5mm, 0.5 cms, 1 cm, 2 cms, 1/16", 1/8", 1/4", 1/2", 1 inch, 2 inches.

This is the working mechanical movement of a wankel rotary engine made into a cufflink. The cam shaft on the end turns the rotor in the housing. This cufflink is intended to be functional if printed in the "Detail" material. Due to the need for tight tolerances between moving parts printing in other material will make this cufflink non-functional. It will still look really cool but it is deisgned for the detail materials. CAUTION: Printing this in a material other than "Detail" will render the mechanical movement of this cufflink NON-FUNCTIONAL. It will look nice just not move. This is my first version so let me know what you think. Update: sorry I can't offer these for sale right now because the tolerances on the moving components are too tight so it doesn't move right now I will be remaking the cufflinks and trying again soon. Thanks for your patience.
