Description

OK look, I know you've tried slippery balls, twisty eggs, and the skull. Maybe you've even already tried The Rock. If you like twisties, I'm confident you're going to love this. Having tested several different twisty models before designing my own, and now having iterated the internals of my own design dozens of times, I am pleased to offer the very finest in ovoid fidgetry.

Included profiles for single-color (no AMS), simple height-striped 4-Color AMS, and 16-Color Full Spectrum.

For the 16-color version you need to use the FullSpec .3mf file, which is NOT what you get from the “Download .3mf” button! Click “Download STL/CAD Files” and then select the U1 .3mf file. This is the right file for FullSpec whether or not your printer is a U1. Just change the machine after opening in FullSpOrca.

What makes this the Egg to Beat!?

Simply put, fine details:

Secure and durable internals. Starting with the basics: the slot and pin architecture has been tuned to maximize strength. Dimensions were drawn with an eye toward ensuring good wall continuity in all key areas. When you slice these models you'll see how important that is.
Rounded-over corners in the center of the egg at the top bottom avoid the 90-degree sharp corners in other designs.
All edges filetted. Sounds simple, but rare to see in these models. Again, improves feel in the hand.
Size tuning. I have tried everything from 30mm to 85; 50-60 is the sweet spot for nearly everyone. These also scale pretty well.
Rotation tuning and options. I have tried rotation/slice from ¼ to ¾ and established 3/8 as the ideal twist at this size. I also include STL files for ⅓ and 7/16 twist eggs. The ⅓ is more “slippery” and runs through the hands better, the 7/16 is “twistier” and plays exceptionally well in one hand. The 3/8 does all things well though and is highly recommended.
Profiles for every user from single-color A1M up to U1 Full Spectrum in 16-colors!

What's that about Full Spectrum?

If you haven't heard, Full Spectrum (FullSpec) is the coolest thing in 3D printing today. Using a fork of Snapmaker Orca created by ratdoux, it is now shockingly simple to use combinations of a small number of filaments to simulate many colors. While it was developed with the Snapmaker U1 in mind, it can be used with any printer that's compatible with Orca Slicer (which is just about everything). I have personally successfully printed FullSpec on a Bambu Lab P1S. That said, the process generally involves a very, very high density of filament swaps, so use on single-nozzle AMS systems is extremely poop-intensive and thus not recommended.

If you're interested in more FullSpec models, here are a few:
