Need Help Designing a Housing for a PD Power Bank Trigger

Hi -

I am great with electronics, but not great with figuring out physical housings for my circuits.

What I want to do is to create a small enclosure that will hold two panel mount USB female connectors, one the standard size and the other a type C. Next to those I want to connect a male 2.1mm connector on a flexible cable, suitable to plug into any device like a pedal found on a typical guitar pedal board.

Inside the small enclosure will be just a small voltage “trigger” that forces a typical PD power bank to put out a constant 9V. I have such a power bank and also have the triggers, so I know the concept works well. I just need help with the design of the small enclosure.

I do not have a 3D printer, but would gladly pay someone to create the enclosures for me. If it helps, the triggers are just 1.5 by 0.5 inches in size, including a standard size USB female. I would then have to create some type of adapter cable that would split the signal from the USB port on the trigger to both the external USB ports.

If anyone can think of a more elegant solution, that would be perfectly acceptable as well.

Thanks in advance for any assistance.

I’ve used heat shrink around those trigger boards as enclosures. Heavy-duty 3:1 or 4:1 marine heat shrink with heat-set adhesive in it.

Elegant it is not, but functional it has been…

You don’t need to have a 3D printer. If you can design the enclosure, you can send the STL files to a 3D printing company.

A buddy of mine had a better suggestion, although yours is a good one. He suggested I use a Hammond 1551-type enclosure and just buy pigtails with the right connectors, thus avoiding the hassle of trying to either figure out or find panel mount USB connectors. Thank you very much for your suggestion though.
