Gripper for Leifheit Click System

We have a  Leifheit telescope handle (Nr 41523, 135 - 400 cm) that we use to clean high windows. Also it can be useful for positioning something high up. For that I already created a universal hook

This time I designed a small gripper. It can be useful where the hook is too simple.

The gripper fits on the Leifheit Click system. However when you have another system it is easy to design an adapter to make it fit on other telescopic poles. Just design an adapter around a M26x1.5 ISO Thread.

I used PETG for strength. 0.2 mm Layer height 15% InFill.
The parts are designed and cut in such way for easy print and for max strength. See the .3mf file for details. It is also best to use some “paint on” supports.

Besides the printed parts you need a M6X20, M3X10 and M3X20 fasteners as well as a rubber band. Use a bit of loctite to fix the M6 nut. A piece of rope, a bit longer then the max length of your telescopic handle is also needed to operate the gripper.

The middle parts you need to glue together. There are some 1.8 mm holes where you can put in small pieces of filament (mac 4 mm) for alignment. Likely you have to ream the holes a bit with a 1.8 mm drill. Maybe you have to polish the M26 thread also a bit, depending on your printer settings (seam etc.)

Update: I have added feet to increase the friction between the gripper and the object to move. It is best to print them with TPU. The lower foot will be able to rotate a bit to align with the surface.

As always when you like the design give me some likes. When you print it publish a make.
