Window blocker for portable AC unit

Needed to block off an outward opening window to vent my portable AC unit.All parts printed in PETG to allow for a little bending and weather resistance.The connector for the host is a little tight but the hose connection has some play to it so it's not too difficult to fit.You'll need M3 bolts and nuts for the vent connections and also for the braces.If you find the board is slipping down, you can print the optional aligner and put a couple of them across the bottom to rest against the inside edge of the window frame.
