Modern (self) Bondage Fiddle with rotating hand-holes, parametric

thingiverse

This is a 3D printable **bondage fiddle**, which consists of 3 layers that are screwed together. For the Hands the shackles have an eliptical fit, so it should sit very snug, while still allowing you to spinn your hands, and perform tasks :D. I split it so it can fit on my prusa i3, and chose 3 layers for printability without support structures and for the hinges. It is also suitable for **selfbondage**, since the lock is easy to reach if on top, you just have to worry about getting the bolt in the hole from the bottom. But don't worry, the lock is pretty much impossible to reach if its hanging on the downside. Also, i recommend having the side with the screwheads facing up when doing self bondage, so you could unscrew them in a emergency. **Just measure your necks diameter** (at the broadest place, or measure the circumference and calculate) and round it up a little. Note that your neck is eliptical but the fiddle has a round hole. If you need another Size, just modify it in the Fusion360 file (by changing the parameters). The same applies if your hands don't fit in the shackles, the standart **sizes** of the **hands** are: **S = 54mm x 41mm.** **M = 59.5mm x 44.5mm.** **L = 63mm x 48mm.** (with times height, as measured by an calipher) You can use the shackles with one or two screws, and i'd recommend to glue each halfes together. Either have all the cutouts on one side for it to be screwed locked to your hands, or move them to the other side for it to hold onto your hands without screwing them shut. They won’t open anyway as soon as they’re inside the fiddle. Just try it out without glueing them together first. I also did a version that doesn't have nuts, and can be used with regular M3x20mm bolts, instead of the uncommon M3x23mm bolts. It also doesn't require nuts anymore. I did so by decreasing the size of the hole. I recommend to use a threadcutter though. This version is only avivable as an .f3d file though, so you need to have Fusion for your sizes. *~Enjoy your fun bondage times!~* Also make sure to join my group for future releases: https://www.thingiverse.com/groups/bondage ###**Hardware required:** **26 x M3x23mm** hexagon socket (allen) screws **26 x M3** hexagon nuts **9 x M4x20mm** hexagon socket (allen) screws **9 x M4** hexagon nuts A rather big **Padlock** **Glue**
