Origami Press #2: Yoshizawa Butterfly

Origami Press #2: Yoshizawa Butterfly 2016 1512 mathgrrl
This 3D-printed origami press is a helper for folding a beautiful and elegant butterfly model designed by Akira Yoshizawa. One of the final folds pulls the paper together past its natural fold line, which is what creates the organic, curvy shape of the finished model.

3D Printed Origami Press – Miura Fold

3D Printed Origami Press – Miura Fold 2016 1512 mathgrrl
This weekend we’ll be headed to the MOVES 2019 Conference in NYC at MoMath, organized by mathematicians Josh Laison and Robert Vallin.  This year, MOVES is origami-themed and features keynotes by Erik Demaine and Robert Lang. In honor of the occasion we’ve decided to design 3D printed “origami presses” that push crease patterns into origami paper…

Mega Menger!

Mega Menger! 640 480 mathgrrl
The NYC Level 3 MegaMenger sponge at MoMath is done! That makes us one of 11 locations so far that have finished a Level 3 Menger sponge as part of the worldwide MegaMenger project. At the moment at least 10 additional Level 3 sites are still in progress, as well as numerous completed Level 1 and 2 sites, which puts the project at 77.4 percent complete… // Hacktastic

The T-word

Tape. It is not allowed. Origami models are traditionally made with one piece of paper (Robert Lang has some amazing examples) that is only folded – never glued, taped, or cut. Modular origami follows the same rules – no glue, tape, or cutting – but allows multiple pieces of paper (Tokomo Fuse makes beautiful modular designs). But guess what, I’m not Tokomo Fuse or Robert Lang, and neither are you… // Hacktastic

Level Two

Level Two 640 480 mathgrrl
Time to level up! There are many ways to assemble a Level 2 from Level 1’s. One way is to use more general forms of tripods; this is what Jeannine Mosely’s Level 3 sponge project did. We need something quicker, more accessible, easier for everyone working on the project, and that really shows off fractalness. The idea we have may or may not work, but either way this has “hacktastic” written all over it… // Hacktastic
