4 Inch Duct Flange

Unable to find a nice looking flange to finish off the inside of a dryer duct, I designed this one to serve the purpose. It is printed on a JG Aurora A5S, with 0.25mm extruder and 0.1mm layers and a 4mm Brim. it is designed to fit over a 4 inch aluminum duct and fixed in place using wood screws. This was originally designed for my Glowforge installation.

This design can be used for personal use only. I do not authorize its use for sale of any product derived from its design, by anyone or any company.
