Flip Lock Flex River Fins for iRocker SUP

myminifactory

I wanted to be able to take my iRocker Cruiser down shallow rivers without the worry of smashing up or losing the supplied rigid fins as well as reducing the likelihood of performing a surprise superman off my board. iRocker uses a proprietary fin box design so there aren't many options out there to purchase for this application. And so my maker mind went to work. You'll need to print a mirror image of each base. Also, I printed the pin separate so I could orient the layers for strength. These were printed in two materials:The base halves and pins are printed (solid) in carbon fiber filled PLA from SUNLUThe flexible fins are printed (70% triangles, 3 layers and 3 perimeters) in polymaker PolyFlex TPU95   Post-PrintingAssembly is achieved by simply gluing the base halves together with the flexible fin sandwiched in between. After the glue sets the pin can be pressed in and glued. I used CA glue and it works well. Additionally, when in the board the fin box helps to keep everything together.
