Forced cock'n'balls display...

I got the idea, to make a device which would keep my cock 'on display'.

I've made the device from a 5mm thick piece of plexiglass, purchased at my local DIY-shop.
The bends are made by means of a heat-gun and a vice. Put the plexiglass in the vice, and heat it until it becomes soft and pliable.
   
As you see above, the device can be used with different 'toys'. From left it is 1/a bolt and a ring, 2/a U-bolt with padlocked nuts, and 3/a vacuumized carafe and a rubber-disc.

Here you see the device 'on it's own', with the shoelace keeping it 'in place'.

   
Here you see the device, with the bolt and the ring mounted,
     
-and here I've put it on.

     
Here I've mounted a U-bolt - with padlocked wing nuts,
 
-and here I've put it on, with my cockhead locked in place.

   
Here I've replaced the steel with a vacuum-carafe along with a rubber disc (in order to secure the vacuum).
Next to that, I've pumped air out of the carafe.

   
Well, then I got around to make a proper waistband, and then I mounted my 'pipe-holder' - as 'cock-holder' as you see. 
-and then came the idea, to let the 'pipe-holder' hold one of my 'vacuum-bottles', upon which I let my vacuum pump remove some of the air inside it.
I'm just about to abandon my previous statement, that vacuum cannot be utilized to lengthen my cock...
