Irish 8 Cuff

thingiverse

Just a simple Irish 8 style cuff that locks with an external padlock. Hole should fit most ~1/4" shackled locks, but I also included an adapter pin that allows you to use the smaller ~1/8" padlocks commonly used (the mini Master locks of the same style with ~.136" shackles fit too). Height of the cuff is 1.5". Both halves are identical, just flip one over for the other half. I used a 3/16" pin for the hinge, but if you don't have any hardware lying around I included a simple STL of a 3/16" pin. It's exactly .1875", just like hole, so it will be a very tight fit. File/drill out the hole or sand the pin as needed. Included four sizes of cuffs, these are the interior dimensions of the ellipses for each: Large: 3.0" x 2.5" Medium: 2.75" x 2.25: Small: 2.5" x 2.0" Extra Small: 2.25" x 1.75" You'll need supports for the hinge, and possibly the lock hole depending how well you can print overhangs. And I know the print quality in the example pictures is bad, the filament is old.
