This remix is 99% like the original however I fixed some errors in the original STL (strange print-in-air segments). I also made it slightly more adjustable (more slop in the mount holes).
I recommend you print is something pretty strong like PC blend or maybe PETG, the weak points are in bad spots (along layer lines) where the mount must flex to fit the banana. I printed in PC Blend Carbon Fiber; really nice result.
There's some difficult to print overhang areas, might take some experimenting with layer height to dial in a good print. For CF PC Blend 0.2mm worked the best, anything less and the layers retained too much heat and would sag. I think for PLA, 0.1mm would look amazing (use Prusa slicer variable layer height in difficult areas).
Print with at least 6 perimeters.
