AEG Comfort 6000 hose adapter

I use this adapter to fix the air hose of my AEG Comfort 6000 air conditioning unit to a plywood sheet inside my window.

It was easier for me to cut out a rectangle hole (200x100mm) in the 6,5mm plywood sheet, so the adapter includes a backplate for it. The front part needs to be printed twice. The bottom one is permanently attached to the back plate and allows the hose to be easily attached to it. With the other half of the front plate the hose is securely fixed to the adapter.

The holes in the backplate are 6mm in diameter and intended to be used with M4 heat-set inserts (I am using the ones from CNC Kitchen).

I printed all files in PETG.
