So, there is my simple and cheap solution to this. I got this idea when I saw a DIA film portable viewer called F-Scoper from CENEI at Fleamarket last week (in German Diabetrachter).
For getting this done you need such DIA viewer and two pieces of rubber band. That whoops the price to aproximativelly 1.01 Euro. You will need to remove the back of the DIA Viewer and follow the instructions in the following video:

Excellent workaround, keep it up.
