Here's the Stabb-it, a cardboard pencil holder two school colleagues, Kim B. Deland and Simon Hamel, and myself made!
Easy to build with laser cutting (or with an x-acto knife) and fun to use, you literally "stab" the pencil holder with your drawing/writing stuff! Submitted by DIN 2012, Université de Montréal, industrial design program, for the Instructables Sponsorship Program.
You will need:
1 cardboard sheet of approximately 385mm (15,16 inches) of height and 590mm (23,12 inches) of length. (I found mine in the recycle bin and adjusted it to fit inside the laser cutting machine)
1 4 inches long bolt with a diameter of 3/8 inch
1 3/8 inch nut
1 3/8 inch washer
The illustrator file provided with the instructable for the laser cutting machine (there's also a pdf version
Step 1: Laser Cutting
Send the illustrator file to the laser cutting machine with an accordingly fitting size cardboard sheet depending on the size of your machine if the suggested cardboard size doesn't fit. You should end up with two spare cardboard squares out of the 24 on the .ai file since you'll be needing 22 of them later on. (the two extra squares are not included in the picture)
