LG LP0910WNR portable room AC vent hose connecter

Really was hoping that someone had already done this since It was a little complicated and I had not made much more progress on learning a CAD program.
This mimics the stock connector for the portable room AC on the back and connects a 5 1/4 OD vent tube to it. Lets me use the cheap 5 1/4 hose as an extension for the stock hose.
PETG used for the heat resistance and to save the hassle of venting outside during the print. ABS would work a little better except for the venting requirements while printing.
