After about 30 trials, there is finally a good k'nex adapter on the internet! I am using this for a new type of model roller coaster (https://hackaday.io/project/194177-realistic-roller-coaster), but I think this will be useful to many more people.
This adapter grips comfortably, twists and locks into position in the Hot Wheels track, and is still adjustable along the length of the track. Additionally, a K'Nex piece fits nearly perfectly even after many insertion and removal cycles without breaking.
When slicing, be sure to paint the seam on the side of the adapter. The default is to split it up the middle, which will cause it to split over time.
I believe I printed with .2mm layer height and with PETG filament. I think just a default number of walls as well.
The source Fusion 360 file is included, but contains some failed attempts that are hidden. (the history is not cleaned up)
