Inspired by the well known mobius strip (discovered by August Ferdinand Möbius in 1858), an interest in the unusual, and 3D modelling, I created the Twin Rail mobius pendant.
A half shell and 3 rails form a bearing-like structure to encapsulate a train of 6mm balls in a mind-warping cage with a twisting, fascinating movement bringing to life the only pendent of its kind in the world.
Includes a 4mm loop for attaching to a necklace or leather cord.
See the photographs with retro-fitted 31 6mm chrome steel ball bearings... in the bottom photo, the balls have been heated until they 'blue'... check out the video to see how they move by clicking on the little icon below the camera above.
Note: this item is the shell alone, you will need to aquire and fit the balls (31 x 6mm or 29 x 1/4 in) as well as a suitable necklace to hang it from, a 3mm leather cord works well.
A mobius strip pendant inscribed with End = Beginning
This model was designed by request to represent the cycle of relationships - the end of one relationship leads to the begining of another. The cycle, as with the mobius strip can be endless.

A pair of 1.5mm square cross sections makes a sweep around a three pointed 'circle' twisting and intertwining along their way to form this mobius style piece. Most suited as a pendant.
A larger version, with 2mm square cross section rails can be found here;
