Skylight Window Crank Hook

cults3d

Hook for a standard 5TPI extension pole so open a skylight with the loop or hook type crank. My pole broke and a replacement is $40. An extension pole is only $10, but it doens't have a hook, but I have a 3D printer!!! Stole the threads from jsnodgrass's "Hook for Cristmas Lights", thanks, 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 found Gorilla Glue first, but I suspect that's overkill. Probably even wood glue to fill the space would work. I gather there's a 4 thread-per-inch (4TPI) thread (because the thing I remixed this from said so), 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 it's paces.
