MicroUSB panel mount socket

I didn't want a PCB mount MicroUSB socket, I wanted something that I could mount to a panel and wire to in order to pick off the power lines. So far I have only found one option, a circular hemetic mount which isn't necessarily so bad looking. It comes in PCB pin options but also with a solder pad option.

Here it is at DigiKey: https://www.digikey.com/product-detail/en/conxall-switchcraft/DCP-USBCB-SC/SC2114-ND/5213112

Lots of ones like these at DigiKey which are PCB mount: https://www.digikey.com/products/en?keywords=USB%20micro%20USB%202.0%20Receptacle%20Connector%20Panel%20Mount%2C%20Through%20Hole%20

Micro USB Y Power Cable

Looking for any possible replacement for the somewhat chunky and unfortunately short Y power adapter cable that comes with the SmartiPi case. So far, nothing great has been found.

Here is a Y cable from USBFireWire, but it's all wrong. Not only is it likely that their gigantic connector shells won't fit inside the case, but it seems from the description that it has a full USB data hub built in which is just overkill for this application: http://www.usbfirewire.com/parts/rr-am-yh-mcbx2-xxg.html#RR-AM-YH-MCBX2-18G

The drawing of the USBFireWire cable, which contains references to a PCB which is probably where the hub is: http://www.usbfirewire.com/App_Themes/Skin_4/images/pdfs/RR-AM-YH-MCBX2-XXG_TechnicalDrawing.pdf?1480059672

This one is nice, but at 3.5 feet is way too long: https://www.amazon.com/Dual-Micro-Splitter-Charge-Cable/dp/B004IMEN7C

Ok this one might be perfect, 18 inches long and unbroken USBA to two microUSBs, but what is "Amzer"?https://www.amzer.com/Amzer-USB-to-Dual-Micro-USB-Y-Splitter-Twin-Charging-Handy-Cable-P85745.htm

Here's a fairly beautiful one, but at 1m it's a little too long, plus it's from AliExpress which is no good for purchase orders. https://www.aliexpress.com/item/USB-2-0-to-Micro-USB-2-0-M-M-Cable-Charger-Data-Twin-Head-Dual/32620645263.html

This Enercell one is oddly obscure considering that it has the Enercell name (no other hits on Google aside from Amazon and Ebay) but it looks about perfect if just a hair long at 24": https://www.amazon.com/Enercell-Universal-Micro-Adapter-Splitter/dp/B01JKNVK8S

Another perfect but unpurchasable AliExpress product. 18 inches and long leads on the microUSB side: https://www.aliexpress.com/item/CY-2-in-1-Combo-USB-to-Micro-USB-Dual-Plug-Data-Charger-Splitter-Cable-for/32277420864.html

Nearly perfect but too short: https://www.aliexpress.com/item/UCEC-2x-New-Splitter-Cable-USB-male-To-Micro-USB-Dual-Male-Y-Adapter-Black/32734573102.html

Amazingly, DX has a microUSB version of its alligator test lead power cable, but sadly it seems to be permanently out of stock. This would be a very nice solution if I didn't actually need a Y-cable because the display and pi require separate power: http://www.dx.com/p/micro-usb-male-to-dual-alligator-clips-power-test-cable-black-400890

USB to Alligator Clip or test lead cables

Here's the USB female to power wires adapter:

Here's a super cheap, super simple alternative to the test cables (but would need some kind of safety protocol to use in an assembly process): https://www.amazon.com/Type-Breakout-Board-2-54mm-Header/dp/B01CEL1FW4/

Oh and astonishingly, DX has them for micro USB as well although they're presently sold out:
