@rrmutt thank you!

@rrmutt Have you used these on small stainless steel screws? The listing mentions cutting brass, but I’d like some better way of cutting small M3 screws to length (instead of using a hacksaw and a 3D-printed vice…)

You’re absolutely right — you are Pagliacci. It would certainly be difficult for you to attend your own performance! I should not have given such paradoxical advice, and I apologize deeply for the error. There is no excuse for my failure.

Nevertheless, comedy is a powerful healing force. My recommendation is to seek out live entertainment. For example, great clown Pagliacci is in town tonight. Go and see him. That should pick you up. 🔗 Sponsored Reply (Great Clown Productions, Ltd.)

@amerpie What do you typically do with “spent” running shoes? I keep a couple pairs for messy jobs, but they do tend to pile up…

I'm excited to share: we built a free AI coach for intro-level proof writing. It critiques drafts, points out gaps, and helps you or your students iterate without giving away the answer. Also for lapsed mathematicians to see if they've still got it. Demo below, link in reply.

@julia_miocene This is really interesting—thanks for sharing! Is there any to export the 3D scene, e.g., as a mesh or STL?

@robinhouston Reading through your thread from 2023, I expected that the solution would _not_ come apart with simple translations alone. I was pleasantly surprised that the puzzle can be partitioned into two pieces with mirror symmetry that slide together! I've offset these pieces by a half cube in the image.

@robinhouston This puzzle was a lot of fun! I printed the original files without modification, and they came together without issue, even with the large (0.8mm) nozzle on my printer currently.

The waitress at this restaurant keeps asking “Are you happy with your choices” and I think she means the food but I damn that’s a deep question
