Parametric Lasercut Bondage Fiddle

thingiverse

# Summary This is a re-creation of babbak's 3D-printable [Bondage Fiddle](https://www.thingiverse.com/thing:4673810). This one designed to be cut from several layers of plywood on a lasercutter. # Customizing The DXF files that are included with the thing have a size for the hands of **56mm x 44mm** and a neck diameter of **115mm**, resulting in a fiddle for a rather small person. However, all values are customizable. This also includes parameters like - distance between neck and hands - diameter of dowels, hinge pins, bolt - number of layers and general *bulkyness* Just adjust the parameters and export the sketches **Bottom Layer**, **Middle Layer** and **Top Layer**. Bottom and top are almost identical, except that the top has a square hole. This is due to the shape of the screw I'm using to lock it, you should definitely customize this. # Assembly Depending on the number of layers you want, print the according number of top, middle and top pieces. Pro tip: Don't mix the pieces up during the process or during transport.... Use dowels (mine have a diameter of 8mm) to align the pieces and glue them together. Hammer the material for the hinges for the holes (I used the same 8mm dowels, because why not). Right now, I am using an 8mm screw as the bolt, but I plan something different for the near future. # Changelog ### 2021-11-15 - Re-modeled the Fusion360 file. The cuff-inserts are now separate objects, which solves some issues when re-parameterizing. Thanks to bababbak for making the suggestion. This should solve the issue of the "hand-holes" randomly closing when changing parameters. - Added a little bit of space between the cuff-inserts and the fiddle. This allows the cuff-inserts to rotate even without sanding - Updated the default parameters: The fiddle is not shorter, overall, making it more comfortable to wear - Removed some of the extra alignment holes. Two on each part are enough. - Removed some pointy bits, so you won't pinch your skin when closing the fiddle
