In this Instructable i want you to introduce my Universal Hook where you can hang every stick based Item like a cane, broom, floor wiper or crutches on the most places like handles, backrests, Tables stair-handles ...

The main idea behind this project was to make a hook for my father in law`s canes. He is handicapped due his Parkinson disease and so he needs always a cane placed beside him. Canes have the bad property to fall always down on the floor while they are balanced again a chair or table. First i had done a hook with a fixed stick diameter, but the problem was, that the canes vary in the diameter were my father in law has at home.

So i developed a shape that can be fixed on almost every diameter of stick only with the help of two cable ties.

My use at home is at the stick of the floor-wiper. These wipers have a hinge for easy reaching every edge while wiping. This advantage is also the disadvantage, because they always tilt if you try to place them somewhere, while you have to wash the wiping cloth in between.

Until the partial switching and manipulating of gravity becomes real like in the novel "Influx ("Control" in German edition)" from Daniel Suarez , these hooks may help you.

Step 1: Let`s Gather the Parts and Tools

There are not much parts you`ll need beside the printed parts:

1 Screw M3 / 20mm - I recommend a Allen Key variant

2 Washers M3

1 Nut M3 - I recommend a lock nut. Otherwise you can fix the nut with a drop glue to prevent from loosing

2 Cable ties a least with max 6 mm height and a length dependent to the stick. I recommend ties with steel tongues.

The tools:

Screwdrivers or Allen key - depending to your screw

A small file

A 3mm Drill

A Sharp Knife

Step 2: Print the Parts..

I` ve printed the clamp with a layer height of 0,2mm because the holes for the screw will get finer and the edges look smooth. The hooks can be printed "quick and dirty" with 0,3mm height and 40% infill. Also if you split the print in hooks and clamps you can do them in different colors.

As material i used ABS because i thought it`s a bit more flexible then PLA and will not break easy when the cane drops on the floor.

After you have harvested the parts from the printer it may be necessary to drill out the hole for the screw. I always bore printed parts by hand with the drill fixed in a wrench and the part rotating by hand over the drill.

Step 3: Put Em Together

Well, there is not much to explain on this place. The mounting explains it self in the pictures. There heaviest point is to put the screw in, and place the washers under the screw-head and the nut.

Now fix all with the ties strongly on the stick..

Hints:

Fix the nut slightly and not to tight so the hook can be moved easy.

The 20mm long screw can be cut by a little iron-saw and filed on the end after it has been shorten.

The hook may be filed a bit (depending to the print result) in the height where it contacts the clamp.

The cable ties should be cut with a sharp knife close to the lock to prevent to get hurt. I know what i am talking about :( In my job i scratch my hands often on cable ties who get quick cut by a wire cutter.
