Flightclub PrOton R Fin

thingiverse

This design comes with a warning: for those who faint at heart. Let me explain the concept, this print serves as an excellent method to attach the fin to the top of the PrOton R frame without resorting to screws or zipties. The design must be snug enough to stay in place on its own, but this also makes it challenging to install initially. To succeed with this design, you need to print it on its side with supports, which will result in a less aesthetically pleasing print, but provides the necessary strength. When installing, I found that twisting and pushing the front end into position works best, followed by prying the back into place while continuing to push and shove the rear section as far as possible.
