This comes in handy when camping, on the road or if the bathrooms are disgusting!
If you can't find a use for this, then you obviously have not been in a situation where you've wished you could pee through your fly... If the thought offends you, then please do not read on.



Step 1Materials

What you need:

Scissors
Lighter
Plastic cutting board (the pliable kind)
Sharpie
Paper
Two pieces of wood (I hear thick books can also work)





Step 2Use the paper/carboard to make a stencil.

Fold the paper in half and draw a curve across one edge. (the crease is on the bottom). Next cut along the curved line and unfold your stencil. The length of the STP device is up to personal preference.



Step 3Use your carboard stencil

Place it over the plastic cutting board and use the sharpie to mark the edges. Carefully cut out the shape out of the plastic cutting board, and fold it in half to create a crease. (hint: you may want to use an object to flatten the crease out)



Step 4Melting the edge

Ok so please do this step outside as there are likely fumes created from melting the plastic. Get the assistance of someone else if you don't think you can do this safely.

Place the folded plastic piece between the two pieces of wood. Place it so that the curved part is poking out slighting from the wood (a few mm)

Now i was unable to do this for the second photo (as I was holding the camera), put pressure on the wood so that the plastic parts are together.

Use the lighter to melt the plastic together. Don't stay too long in one place, instead wave the flame gently back and forth for about 30 seconds. The intent is to seal the plastic not burn it. When the plastic is hot use the wood to press over the hot seam in order to seal it properly.

In order to get the full curve, you will likely have to adjust the plastic and melt the rest of it. Take your time.



Step 5The finished product.

Test the product under running water to make sure the curved end is leak proof.

How to use it? Practice at home first to make sure you are ok using it. The open end goes out through your fly. Prop the STP open slightly and place it gently against yourself. Make sure you angle the tip downwards slightly in order to assist with voiding. Voila!
Wash after every use.

You can stow it away flat in your pocket or anywhere else.

Use scissors to trim it for a comfortable fit if needed.
