Handlebar Mount for Extra Equipment (clip On) Bicycle

I've made a simple device for mounting extra equipment using the stem.

I did this so I can keep using the complete handlebar for riding.

PVC Tubing (Diameter slightly bigger than stem)
round bar (length according to the amount of extra stuff you want to use)
flat piece of iron (to connect round bar with pvc piece)
Rivets (you can use small screws)

Step 1: Main Piece

This is the main piece,

sized by trial, filing away small bits to get a good fit

make it long enough so it covers the whole stem
the front bit is wedged between the 2 top bolts of the stem (see final picture)

Step 2: Ready

This is ready, but variations are possible,

you can use a longer or even better looking connection piece or put the round bar underneath
whatever you prefer
