Skylight Window Crank Hook

thingiverse

Hook for a standard 5TPI extension pole so open a skylight with the loop or hook type crank easily. My pole broke and a replacement costs $40. An extension pole is only $10, but it lacks a hook, yet I have a 3D printer! I borrowed threads from jsnodgrass's "Hook for Christmas Lights", thanks to them, that saved some time. I had to glue it to the pole to keep it from unscrewing when I tried to open the skylight. I discovered Gorilla Glue first, but I suspect that's overkill. Probably even wood glue to fill the space would work. There's a 4 thread-per-inch (4TPI) thread because the thing I remixed this from mentioned it, but I'm not sure where that's used, the poles I know about all are 5TPI, so I didn't bother with any other version. Full disclosure: Gearbest gave me the CR-10 that I printed one of these with, so I feel sort of obligated to put it through its paces.
