Printed my duct in ASA-X at the time, printed the (straight) struts with a hole inside and epoxied 3mm cfk rods inside. Then added a layer of cfk only on the outside of the duct, easy to sand.  
See here: [Daniels (un)geared inflatable (slowly built) - #18 by JvdZ](https://foil.zone/t/daniels-geared-inflatable-slowly-built/8069/18)

Although I don’t use this duct anymore, it was solid enough to not deform under load, it worked quit well.
