This Pinch Type Holder\Bracket was designed to replace a Hand Operated Hot Tub Pump with a cylinder diameter of 1.225”.   I have since scaled it down to hold other tools such as Brooms, Rakes and such.  It has a height of 2” and is in mm.  I print it out with a resolution of 0.29 mm and an infill of 15%.  It has a height of 2" but sometimes I just halt the printing when it is the height I need.  I did not put mounting holes so just drill out with 0.144" drill and use #6-32 wood screws. Happy Hanging!
