thingiverse

I originally created the initial version of the compact 130mm fin specifically for river stand-up paddleboarding on the Isar south of Munich. Upon construction, I discovered that those fins can be easily manufactured without the rectangular washer, screw, and possible FinKey tool required for mounting. Simply by printing the rectangular washer in the correct position and size - then simply slide in the fin and print it as thick or thicken it up with tape to fit exactly into your fin-box. This release is now already the third 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 also be printed, but I doubt that long-term stability is fine (anyway someone should test it). The pin is usually Ø5 x 15mm, also available as standard part - use ISO 8734 Cylindrical Pins, stainless steel 1.4301 or better 1.4576. Print Settings Printer: Cubicon Single 110F Rafts: No Supports: Yes Resolution: 0.4 nozzle, 0.2 layer Infill: 40% Notes: Setting I tuned in Simplify3d: 60 bottom layers, so the complete insert part is really stable. 40% infill in the fin, 3 outer layers, 7 top layers, For PETG I used: 220°C extruder, 75°C bed, 40-50°C chamber, if available How I Designed This generate your own awesome fin design with this tool: finFoil.io http://hrobeers.github.io/finFoil/http://sourceforge.net/projects/finfoil/files/ donate for this cool piece of software!
