i noticed that on my max g3 the nut and thread were completly open, so i decided to make a simple model of Nut/ Thread protector for segway max g3.

print with PETG and 100% infill and i recommend to use adaptive layer height so it looks nicer, print it with support as shown on the photo. i also optimised support settings for cleaner removal, and i used thick double sided tape to mount the protector on the nut. You can try to use hot glue gun, but i have not tried it and i am not reponsible for any damage of the scooter if it may happend. And i did not try them in an actual crash, so i dont know if it will fully protect the thread and the nut,.
