Designed these parts to hold my window open and attach a 4 inch exhaust hose from my P1S. This fit my window, however please test fit the 15mm wide prop before printing larger pieces for your own to verify fitment.

-Fits window thickness of 32mm.

-Print all parts besides the pins on the flat side surfaces.

-3 walls at 5% rectilinear infill is recommended to conserve filament.

-Left and right end pieces have a wider flat end for better seal.

-Left end piece is meant to be used with this magnetic hose adapter. Attach with JB Weld or double sided tape: https://makerworld.com/en/models/374008#profileId-273985

If unsure and want to test if this will fit your windows thickness, I would recommend printing the 15mm wide model first. If it fits, measure the width of your window and print the appropriate parts needed. Every part connects with 2 printed pins and is recommended to be permanently bonded with adhesive or tape for a better seal.
