Description
Given that the twintip fins normally only have one engaged at any time when the board is planing, I figured that there should be advantages from an asymetric design. (see my original symetric design too)
Sharper end to tip of board.
Note that because they are asymetric, I've created them in pairs and you can use them in two ways:
1:curved side to outside of board. (more grip)
2:curved side to inside of board (more lift)
V1: slim, for M4 screw.
V2: fatter, for M5 screw. More taper at top of fin.50mm screw spacing
V3 as V2 but 38.1mm screw spacing.
Prints well with Pet-G T-Glass etc. If using nylon, not 618, it warps too much and it's too soft anyway.
