Assignment for week three (February 12, 2014)
Week 3's session was a lecture about different cutting tools.
This came as the right time as I FINALLY managed to install fab
modules and dependencies on Ubutu 12.04 - running on VM on muy
Mac. This week assignment entailed designing, making and
documenting a press-fit construction kit. I had a look at previous
projects regarding press-fit, in order to get inspiration.
So, I have a 3D printer and feeding it material has been rather a
daunting task. It is to this end that I decided to design and
fabricate a material spool for it. Since well I did not have the
Edge Crush Test (ECT) cardboard at the time of my experimentation,
I used a 3mm Eska board which I had in my lab. Eska board is a
graphic solid board made of 100% recovered paper - with a lay
flat, stay flat properties.
Since well I was more familiar with Open Office Draw (Yeah, I know
- I'm old school like that) and made my 2D design. I also played
around with Corel Draw and finally, with Inkscape. I viewed
Inkscape tutorial videos to get the hang of the software. So, I
decided to work on OODraw.
I had to laser cut several copies, continuously modifying the
press fit.
Well, I do not have a fixed FabLab, so I use the laser cutter in
the Mobile FabLab - and was fortunate that it was not out making
some rounds in schools:-) So, here is the final fabricated project
- which left my hands with lots and lots of char.
