Grommet for mobile air conditioner hose 150mm

Grommet for mobile air conditioner hose 150mm

A simple grommet that I created to get hot air from the air conditioner through a polystyrene board in the window.

It is a simple and easily printable model. It consists of two parts, the main one with the grommet and the counterpart on the outside. In the corners there are holes for 6mm screws, which connect the two parts and create a fairly solid and durable grommet. But it can only be used with a chimney

I print from PETG

layer 0.28

3 perimeters

10% infill is enough

Supports YES

Variants with a chimney 32, 42 and 52mm for passage through boards of different thicknesses.

Wedge to block the second half of the window so it doesn't open
Spacer, if the piece on the opposite side needs to be supported
