Spinner Screw Balanced

thingiverse

This balancer can be adjusted by turning three carriage bolts in and out of the three arms. When the balancer is held upright, it can be balanced so that none of the bolts will shift towards the lowest position. The o-rings exert more pressure on the bolts (they could fly out at high speed), but they also make the balancer easier to grip in your hand. I chose standard hex nuts and bolts for the thumb pieces just to maintain a mechanical look. The second version is stronger and holds a tighter grip on the screws. Extra Materials: + 1 x 608 skateboard or fidget spinner bearing + 1 x 5/16-18 x ½ long Hex Bolt (for thumb piece) + 1 x 5/16-18 Hex Nut (for thumb piece) + 3 x 5/16-18 x 1 long Carriage Bolts + 3 x #204 O-rings (3/8 ID x 5/8 OD)
