Description

I Originally Designed The First Version Of The Small 130Mm Fin For River Sup'Ing On The Isar South Of Munich. During Construction I Discovered That Those Fins Can Be Easily Constructed Without The Rectangular Washer, Screw And Possible Finkey Tool Needed For Mounting. Just By Printing The Rectangular Washer In The Correct Position And Size - Then Just Slide In The Fin And Print It As Thick Or Thick It Up With Tape To Fit Exactly In Your Fin-Box. This Release Is Now Already The 3Rd Version And There'S Still Room For Improvement. Next Will Be A Longer Fin With Plug Connection In Between And Then The Integration Of A Propeller Or Even Better A Remix With This Jet Propulsion Pump Http://Www.Thingiverse.Com/Thing:976225 >:-) The Pin Could Be Printed Too, But I Doubt That The Long Time Stability Is Fine (Anyway Somebody Should Test It :) ). The Pin Is Usually Ø5 X 15Mm, Also Available As Norm Part - Use Iso 8734 Zylinderstifte, Stainless Steel 1.4301 Or Better 1.4576.
