The gag for multiple purposes is making progress.

  

I have planned the following attachments:

• Holder for ashtray
• Holder for toilet paper roll
• Holder for glass
• Adapter for vac u lock
• Holder for pocket rocket
• Whistle
• Adapter harmonica
• Connection for breathing
• Connection for liquid
• Connection for gas mask hose

Here is the progress of some of these attachments

I have successfully completed the toilet paper holder. It came out exactly as I planned.

 

The whistle itself also works. But I would like to have a deeper tone.

 

The prototypes for the connection for the breathing and the liquid have come out quite well. They now need to be tested extensively.
