Week 8: Lasercutting 4

Today I again went to the fablab to lasercut. All the pieces for the maze of the D. also I lasercutted the plexiglass E and D.

And I made a handle for the last E to turn the gears with and I also lasercutted this one at the fablab. And I cutted the first version of the qr code. The qr code did not work with only lasercutting it. So I tied colouring the qr codes in with black and one with red as well. These two worked because the contrast between the white and the coloured part was bigger than when it was not coloured.
