When hobbies collide - My Raspberry Pi controlling my 3D printer
I’ve finally managed to integrate my Raspberry Pi hobby with my 3D printing hobby. My @nop_head Mendel 90 is now completely controlled by the OctoPi / OctoPrint web interface running on a Raspberry Pi.
I can simply open the web page select the file I want to print (or drag it into my browser) and watch it print via the streamed Raspberry Pi camera 
I am very happy, even the adjustable camera bracket I printed came out well
Very cool! I’ve been looking at doing a similar setup as I recently have moved to a Laptop and won’t have a machine permanently connected to my printer. This would allow me to print and walk away.
Any practicality to having the camera sit near the printhead?
Its actually quite far away, take a look at this photo here: https://plus.google.com/u/0/photos/109352235257103413028/albums/5960936996630776545/5975205884541562322
Its right in the back left corner, can you see it?
The white square thing with the black lense.
It seems to be quite a narrow angle camera though with a bit of a zoom which actually works out quite well as you can see in the screen shot.
Yeah sure, I’ll upload it in a moment and post the link.
Sorry for the delay, had some guests turn up, here you go: http://www.thingiverse.com/thing:239268
Let me know how you get on 
I used a Cyntech case which has keyholes on the back and I just pushed one of the keyholes over the spool bracket bolt and its fairly solid
I use these cases for a lot of projects as they have an optional SD card protector and light bars to the indicators on the front so they are easy to read:
