Take a snowchain, mine looked like 6 times a H with a chain on top and bottom to keep it together.
I don't know how snowchains from other brands look.

First we are going to take the H-shapes appart from the chain.

To get loose H shapes. Put the links that keep the H and the chain together with their back in the vice. an use a screwdriver to open them.
You will need these links to put the H-shapes together later!!

Find someone who is used to handeling power tools to cut the chain.
Cut the link where i drew the red line. On al the H you are using (i used 4)

Now we are going to reasamble the parts to be a toiletpaper holder.

Snowchains aint straigt, so check if the spaces between the holders are even, else turn the chain arround so it is.

I used the vice to close those links from step 2 again, since i didn't managed to do so with a hammer.

It shoot look something like the image now. (arrows point at those links from step 2)

With the snowchain set came also this rubber band with hooks.
I cut the rubber band, and opened the hooks. (in the vice with a screwdriver)

Now attach those hooks to those little loose chains (i used the vice to close them)

And well then you are done

I chose to use the thing that probably gets used to attach the chains to cartires. So people sitting on my toilet may see it is assembled from a snowchain.
