Let kids download and import files on 3D Slash,
Guide them to the candy dispenser files and ask kids to download the virgin plugs of the
dispenser,
45 min’ – Make custom plugs for the dispenser
Show kids how to bring a picture in 3D Slash from the internet, give them several
examples (cf further slides),
Teach them how to crop pictures in a clean way using the chisel, small cubes, and
selection ruler ; then print their parts,
15 min’ – Test the candy dispenser ! (It is adapted for Smarties and Skittles)

Important note : set the yellow ruler so that you don’t cut through all the part,
You can repeat the same process with the top plug:

Note : it is more appropriate to use 3D Slash downloadable version to edit these files because
full features might be needed.

Important notice regarding 3D printing
It takes approximately 6 hours to print all parts of the candy dispenser. Consequently
you will need to print a demonstration model BEFORE the workshop so that you can
show it to the kids,
The demonstration files to print are available at the following link:
http://www.thingiverse.com/thing:849439
Click on the link and download the .STL file to print it on your printer ; OR print it
online at www.3dhubs.com,
Note: if you can’t have access to a laser cutter to cut automatically the plexiglass (to
enable kids to grab the candy when it is down the dispenser), make sure the plexiglass is
shorter than the dispenser core part.

12+ kids can go further:
Modeling of the entire candy dispenser, following dimensions wrote on a whiteboard, taking
mechanical adjustments into account (ex : make the axis’ hole a little bit bigger than the
plug axis’ diameter),
Designing some improvements of the current model,
Inventing new models of candy dispensers,
Learning about Creative Commons licenses, and sharing the modified or invented dispensers
with the appropriate licenses,
