P1X QRCode TAG

## P1X Tag with QR code
A business card for a 2019. Free and open source as everything we made.

### Creation
No 3D modelling software involved.

- Initial image made in GIMP as heightmap (image attached).
- Set to 60x30x2.2mm in Ultimaker Cura.

Qrcode created using qrencode:
```
qrencode -o qr.png https://p1x.in
```


### Print

Printed on 0.20 resolution and 60mm/s speed but take too much time. Good enough compromise is 0.28 and 80mm/s speed. At the end I used Staedler permanent pen for making QRcode black. It needs to have a good contrast.

**Update**
I found that 2mm height is not enough (for my printer). Changed to 3mm and now print is much cleaner. I uploaded both two versions as with slower print the 2.2mm should be good.
