Hi,

This is my simple dust extraction duct connector, i have a dust extraction system in my workshop. i purchased a 2nd set of 100mm solid ducting and found that the new pipe and old were sized differently 1 internally 100mm and the other 100mm exterally. this is my simple solusion to this issue. there is a flat 25mm sholders at each end friction fit / glue the connection and the infil is only 15% making it light for easy fitment and to not require support fixings.

please comment and share images if you print, this is my first desgin and im going to be learning how to design more and upload more everyday. so if there any request for items please message me as i would like the challange/project ideas.

Thank you
