I wanted to take some photos of the recent Comet NEOWISE so needed a quick and dirty way to make a camera to 24.5mm tube adapter. My 3d printer would have a hard time printing an EF flange so instead I just made a tube is bolted to a macro adapter in place of the female EF flange.

I never managed to photograph the comet because of the poor quality mount in my telescope; by the time I fixed the problems, I could no longer see the comet. Here's a photo of the moon.
