3D model description

A flange for mounting 100mm air conditioning ducting.

Used on the window mounted exhaust panel of my fume cabinet for my RepRap Prusa Mendel. (Short description:

The A/C ducting is standard 100mm ducting, as used in range hoods and bathroom extraction fans.

3D printing settings

Flange Dimensions:
110mm x 110mm x 55mm high

Mounting Hardware:
4x Diameter 4.5mm countersunk holes provided on a 92mm square pitch.
The holes were designed to take some brass wood screws that I had lying around.

Exit Aperture:
You need at least a 98mm hole. Be careful if you make the panel the exact width of the flange like I did in the attached picture. This doesn't leave you with much material on either side of the hole. I cut my wood in a basic grill pattern to leave some more material there.

Usage: Print flange, cut hole in panel, screw down flange, slide ducting over the lip on the end, enjoy the fresh air.

Printed with:
0.3mm layer height
3 perimeters, this allowed a solid printed cylindrical section
3 solid layers
25% infill

You can reduce the layer height, however it will increase the print time.
