Finger Handcuffs
- A joined set of rings styled after Smith & Wesson Model 103 handcuffs.
- Hinged, with catches connected to both chain ends, both cuffs open and are adjustable to accomodate the normal size differences between adjacent fingers.
- Designed as a production piece employing captive rivet assembly. Unfortunately it never progressed past the prototype stage, although there are possibilities as a custom ring. The logo and other decorative elements are easily modified in the model file.

Rhino Model
- Although not a very complex piece there is enough duplication of shapes to benefit from cnc milling, especially when making the initial prototype without molds.
- Being able to simulate motion in Rhino also simplifies designing the catch mechanism.

Milling Strategy
- Parts laid out on plane surface
- Dimples mark hole locations for assembly rivits. The final fit and finishing of the model is done in metal to achieve the best results.Production models would be partialy assembled with cast captive rivets to secure cover plate with molded holes.
- Finish milled with both a fine vee cutter raster strategy for details and an endmill waterline strategy to achieve vertical walls.
