So, I'm stuck away from my pc and 3d printer and with only a sheet of paper for designing. So random ideas season.
Design is based on the assumption pressure goes up the more pee you have in your bladder.
So here's the idea, get one of those urethral chastities with actually good sealing. Connect a tunable pressure regulator. Set the pressure regulator to maximum pressure which will prevent flow and wait for the urge to piss. One the desired urge to piss has been achieved slowly reduce the pressure while trying as hard as you can to squeeze piss out. Once piss starts to flow just turn the pressure regulator up a bit more to achieve the desired control. It is also a good idea to hook up a catheter bag.
If my assumption holds water (pun intended) you should constantly feel the need to piss and if you squeeze hard you let off excess piss yet you still feel the urge. Utterly evil.
A very good idea
For my other future plans(I have many) I plan to cnc the strongest bodysafe plastic or aluminum into a small disk with a hole inside to make a ring that will rest in the sphincter at the tip of my penis. For comfort purposes it will be molded into silicone and will provide better sealing. Luckily for me I can stretch the tip of my penis to fit the disk in width wise down the slit before rotating it. When the screw on catheter and external part is put on the disk should be stabilized and impossible to remove without unscrewing. In the future once I get more comfortable with silicone molding (enema permanent plug) and machining I will try to make a conductive silicone catheter and cage to finally achieve hidden chastity.
For my other idea I had a bit of a problem. I wanted chastity bit it had to be unnoticeable unless you had no underwear and with the size of chastity ballsacks that is impossible to do without a skirt. New idea time.
When flaccid I can push my penis and balls inside myself. The skin of my penis can then be pushed inside myself and stretched to form a pocket inside myself with the tip in the middle. With a disk or small cage for the tip that fits inside that pocket it should be possible to have the shaft of the penis entirely inside and part of the chastity while the tip becomes a sort of clit that is still caged. Unsure the effect when you become erect.
I saw video of a chastity device that completely hides your penis inside your groin but I'm pretty sure it relied on your balls remaining outside to anchor it. Probably a Natalie Mars clip.
I've also seen the complete hiding trick you describe done using superglue, it might look neat but I don't much fancy letting cyanoacrylate anywhere near my meat and two veg!

This wont work. The pressure is too high. I have had one of these chastity devices.
Even if you use a catheter you have to test which one fits you best.
If have tried it. I blocked the catheter to see what happens if pressure gets high. Well it was kind of a mess...
At last I found a catheter which sealed my bladder pretty good - but not perfect.

Inflatable?

Ah. But the pressure does rise. That just means you need a good enough seal. Easier to fix

The other thing is that a lot of catheters are just inserted in with a simple condom for retention or an inflatable balloon. Mine will be sealed by an internal ring and external chastity.
I used inflatable catheters. Even with them under pressure it was not tight.
Internal ring? Could you explain that further?
Under pressure, your inner penistube will widen and that ring wont be tight.

Sure! For me there is a constriction in the head of the penis. I plan on making a ring that fits behind the constriction and is connected to the catheter as described. Once the ring is put in the head is then put in a chastity cage with a ring slightly smaller then the penis at full size. The internal ring inside the penis combined with the constriction outside as well as the flesh itself bulging is the seal but that needs to be tested. The plan is that there will be no room for the penistube to widen into. Metal inside and metal outside.
The other thing is that to overcome 30cm of large stiff silicone tube and the metal seal and the chastity cage will require very high pressure. Also the penistube is to be dilated to the maximum.
