Summary Designed this for my new n3ds. if you own one you know the flat stick is not comfortable. In designing it, i discovered just how challenging it is to create one that fits well, as well as, doesn't interfere with the movement of the stick. it goes on, not too tight but just enough to work really well when playing. feels great. Dont know if its the same size for other 3ds models but it prints quick so give it a try and let me know. Instructions best when printed upside down (thumb surface at the bottom)
