Midea 2 in 1 hose adapter for air conditioner Real Cool 35

In this project I designed a Midea 2-in-1 hose adapter for my REAL COOL 35 air conditioner. After several attempts, it now works great. It is crucial to use materials such as chipboard or multiplex with a thickness of 15mm. However, the attached STEP file allows the construction to be adapted as needed.

For 3D printers without a 350x350mm print bed, you can split the front and back in the middle in the slicer to use the adapter. However, this method cannot be used for the lid.

The opening for the 3D print must be 320x200mm so that the 3D print fits in.

Required:
10x M4xØ6,3x4mm threaded insert
10x M4x25mm cylinder head screw
4x M3xØ5x6mm threaded insert
4x M3x12mm cylinder head screw
