Close, the headlamp nut, and windshield wiper nut, and a tool I designed to remove them.
All I need to do is find a place where I can 3D print the tool.
I'm not sure about the nuts, as the thread is an oddball and I'm not sure where to get a tap and die for it.
It's 7/16" diameter, but has 24 threads per inch, where standard 7/16" fine thread is 20 threads per inch... However on my software, there is a listing for 7/16" 24 thread on my design software, but I've never heard of that thread myself...
I could use the tool if I can get one 3D printed in a material that will be strong enough...
My son and his friend say that there are companies where you can have them print it out... I wonder what it costs...
Or wait until next month and see if one of my teachers at school will let me print it...
