Brain wave.
I assume you all are familiar with my Adélie 3d printable, CQC hook pocket hook openable, fully printable utility knife thing. If you weren't, you are now.
Just the other day I had an idea.
Actually, no. Back that up. Just the other day, I remembered the Secret Of Show Business, vis-a-vis another arctic bird adjacent folder, our good friend the QSP Penguin. One thing that's been a thorn in my side with the Adélie since the beginning is that, since a 3D printer is not a lathe, the inevitable overhangs on the crossbar/Axis lock part are problematic. I burned through a couple of strategies for that, including replacing the sharp shoulders with a chamfer (which caused binding issues) or reshaping the slot that the crossbar rides in, and so forth.
But then along came QSP's knife, which deals with the protrusions on the Axis crossbar by making them separate pieces.
Uh. So why don't we just do that?
Duh.
So meet the new and improved, cool and froody, always ready and never glooby, Adélie M6.
Why M6? Oh yeah. Because I also revised the screws to be M6x1.0 a while ago so you can use 12mm setscrews in place of the printed screws if you want to.

Only a dude can be a hoopy frood.
