Although my first love is the cordless 3Doodler Start pen, the corded hot-tip version works too. Here a student is filling in outlines to make a pumpkin in a box.

3D Trinket

A colleague showed me this amazing lesson to make safari-themed trinkets using Tinkercad.com and a 3D printer.
1) Find a free jpg image of an animal from a safari-themed clip art website.
(Obviously any jpg will do, it just so happens that the theme for their school’s prom is “safari.”) I choose a tree from clipart-library.com.
2) Use online-convert.com to change the image file into a .svg file.
3) Log into Tinkercad.com and make a new 3D design
4) Import the .svg image and keep it under 1000 mm (I made mine about 120 mm per side).
5) Make a duplicate of the design, and change the fill mode of the duplicate to outer line.
6) Reduce the height of the initial import to a smaller number (I reduced it to 1 mm high).
The design should now appear as a shape with a higher border around it. Group both into one shape.
FYI: The silhouette mode also works, when it is available (depending on the imported shape).
7) Add a Basic Shape ring to the top of the design.
. Position it and make sure that the height of the ring is the same height as the trinket.
8) Align the center of the ring with the trinket.
9) Group everything and export as an .stl file
10) Open in slicing software (I use Makerbot Print)
AND VOILA

We took a field trip to Adaptive Design Association in midtown Manhattan. They fabricate adaptive accessories — mostly made out of cardboard — for anyone that needs support. Plus “cue cards” for the blind. For free!
Here are some photos from the trip.

The students went to vasedjinn.com and created these models.
I imported them into TinkerCad to reduce the width of the walls and make a drainage hole. After printing and shipping them to the students, they painted them and then planted little plants inside.

I made a work flow to convert the icons used in LEGO Spike and Essentials Robotics programs into 3D prints. The rationale is that some students will benefit from holding the blocks physically in their hands prior to moving them about in the coding programs.

Did the title of the post get your attention? I refer to the “The End” text that a student 3D printed yesterday using a 3Doodler handheld 3D printer. That and other prints — especially bubble wands — are below.

A student gave me the stl file to 3D print this model. I have no idea what the “five nights at Freddie’s” franchise is all about, but it sure has legs.

Math-Kitecture is about students drafting floor plans to learn about math and architecture. This classroom floor plan made it to a 3D print!
