Cube Puzzle Quartet
Cube Puzzle Quartet 628 472 mathgrrl
This year at Maker Faire Bay Area we hung out at the Ultimaker booth and offered a challenge: Solve one of these 3D-printed Cube Puzzles and you get to keep it! All of the pieces can be printed without support, and the puzzles and container are free on Thingiverse or YouMagine. All four are classic puzzles that you can read about in Stewart Coffin’s excellent book Geometric Puzzle Design… // Hacktastic

Girih Tiles for Interactive Islamic Designs
Girih Tiles for Interactive Islamic Designs 628 472 mathgrrl
Girih tiles are used in Islamic art and architecture to create intricate woven strapwork patterns. Their underlying periodic patterns are related to Penrose tilings and predate the formal mathematical discoveries of such tilings by at least 500 years. The basic colorful tile shapes determine overlaid strapwork in the middle, which is accented on the right by concealing the colorful tiles with gray ones… // Hacktastic

From Prototype to Product: Snowflakes
From Prototype to Product: Snowflakes 640 480 mathgrrl
Time to level up and convert our desktop 3D printer models into designs optimized for printing on industrial-level printers. Shapeways is basically a personal remote factory where you upload designs and then have them 3D printed in various materials and mailed to you. That’s easy except for one catch: designing for industrial-level 3D printing is not the same thing as designing for desktop 3D printing… // Hacktastic

Guest post from cgreyninja: First print on the Ultimaker 2 Go
Guest post from cgreyninja: First print on the Ultimaker 2 Go 640 480 Calvin Riley
This walthrough of unboxing and setting up an Ultimaker 2Go was written by 11-year-old Calvin Riley, with only minimal editing and help from his mom, mathgrrl. But what this post is really about is that when you are 3D printing something, errors happen. A lot. Sometimes those errors are from your design, and sometimes they are from the filament or something you forgot when printing… // Hacktastic

Minecraft Star Wars Trash Compactor & 3D-printed Remote Control Pants
Minecraft Star Wars Trash Compactor & 3D-printed Remote Control Pants 628 472 mathgrrl
I think I may have been waiting my whole life to write that title. For the littlebits bitWars Challenge we teamed up with Minecraft adventurers rileypb and cgreyninja to re-create the Trash Compactor Scene from Star Wars. Redstone and pistons were activated by a cloudBit that allowed real-world interaction, and we also included an automatic silverfish generator and a villager to play Chewie… // Hacktastic

The Snowflake Machine
The Snowflake Machine 628 472 mathgrrl
Our new Snowflake Machine uses random numbers, mathematical algorithms, computer code, and SCIENCE to create well over a billion unique and beautiful snowflakes, with an algorithm that approximates the way that snowflakes grow in real life, with branches and plates determined by a random seed. Choose that seed, and then set style parameters to determine fullness and fuzziness… // Hacktastic

Beefy Trophy – Baking meshes into OpenSCAD from Blender
Beefy Trophy – Baking meshes into OpenSCAD from Blender 628 472 mathgrrl
You’re good enough, smart enough, and you deserve a damn trophy. Even if it’s only a trophy that you give yourself for making it through the day, or a meta-award for designing and 3D printing a trophy. (Or maybe a trophy for picking yourself up off the floor after getting the boot in a massive layoff at Makerbot…) We’ll use a python Blender add-on to embed an STL in the Thingiverse Customizer… // Hacktastic

Low-Voxel Stanford Bunny + Voxelization/Minecraft Tutorial
Low-Voxel Stanford Bunny + Voxelization/Minecraft Tutorial 1024 550 mathgrrl
Move over low-poly, it’s time to go low-voxel! In this post we use phooky’s classic Stanford bunny model to test out a fun, easy method of producing low-voxel designs: take a Thingiverse model, use Tinkercad to convert it to a “blockified” .schematic file, then use Minecraft to play around and repair, and finally use Printcraft to export the new “blockified” file for 3D printing… // Hacktastic

3D-Printable Pentagon Tessellations
3D-Printable Pentagon Tessellations 628 472 mathgrrl
If you love pentagons then 2015 was a pretty good year for you, because a new pentagon was discovered! To be more precise, mathematicians Mann, McLoud, Von Derau found a previously unknown convex pentagon that can tessellate the plane. With our new Pentomizer you can use pentagonal tessellations to make pictures, patterns, puzzles, textures, wallpaper, desk ornaments, and cookie cutters… // Hacktastic

PolyBowls – From zero to OpenSCAD in 6 minutes
PolyBowls – From zero to OpenSCAD in 6 minutes 638 483 mathgrrl
This collection of bowls and pen holders were all generated from the same simple OpenSCAD code by changing a few numerical parameters. The main purpose of this design is to serve as an accessible introduction to designing with OpenSCAD. Designing with code is easier than you think; if you have six minutes to spare then you can learn this! Okay, maybe seven minutes. But it’s not hard… // Hacktastic
