1999 Toyota Corolla Clock Panel Replacement

In my '99 Corolla, there is a blank piece of plastic above the radio in the center console where a clock would have been in a different trim level. I noticed during stereo installation that the plug for the clock was still present, and that an unswitched 12v supply was present. As the cigarette lighter is inconveniently located under the drink holder, I thought this would be a good place for a 12v-USB charging connector for mobile device charging. A newer radio install added a rear-mounted USB port and an AUX in port, so I decided to replace the panel with one that would snap in place where the old one was, but offer ports that I needed. I chose USB ports that transferred insertion force to the panel they were mounted in, and paid a ridiculously high price for them. https://www.digikey.ca/product-detail/en/amphenol-commercial-products/MUSB-A511-00/MUSB-A511-00-ND/1242675 The 3.5mm/1/8th in audio jack for AUX in was far more reasonable. http://www.btw-electronics.net/PLUGS-JACKS-ADAPTERS-CABLES-CONNECTORS/3.5mm-mono,-snap-in-type-panel-mount-phone-jack,-70-533,-philmore?sort=p.model&order=DESC&page=4&limit=50 Both connectors had the advantage of having very specific measurements for their needed cutouts online. Some photos show an earlier prototype. UPDATE 17 JUNE 2016: The part has begun to deform due to heat and no longer clips into the dash. This is in relatively moderate Toronto spring temperatures, so using PLA for this Thing is not advised. I will shortly print it again in high temp PLA or ABS.
