*UPDATED* Altered the pins to improve fitment, added a channel for the pi ribbon cable.Description

Do you have a Wanhao i3, i3 v2/2.1 or i3+?

Do you have a Raspberry Pi Zero W and Pi Camera?

Do you want to tie it all together in a sleek, compact system for remote monitoring and control?

Well here's the project for you!

What you'll need:

1. 3 x M6x5mm Bolts (I use Button Head)
2. 3 x M6 Nuts (Regular or Nyloc)
3. 2 x M3x10mm Bolts (I use Socket Head)
4. 2 x M3 Nuts (Regular or Nyloc)
5. 2 x M3 Washers (7mm Max OD)
6. Printed Parts:
   1. 1 x Arm_Piece_Bolt
   2. 1 x Arm_Piece_Nut
   3. 1 x i3_Frame_Bracket
   4. 1 x Octopi_With_Pi_Cam_Body
   5. 1 x Octopi_With_Pi_Cam_Lid
   6. 1 x Pi_Zero_W_Case_Holder
7. 1 x Raspberry Pi Zero W + microSD card (With OctoPi installed)
8. 1 x Camera Module for Raspberry Pi Zero W
9. Optional Extras:
   1. 1 x DS18B20+ Temperature Sensor
   2. 1 x 4.7k Resistor
   3. 3 x Small Pieces of Heatshrink

Instructions:

1. Print all parts.
2. Gather needed parts.
3. Install your Raspberry Pi Zero W into the case ("Octopi_With_Pi_Cam_Body" + "Octopi_With_Pi_Cam_Lid"). The Camera Module ribbon cable should fold under the board, and sit nicely in the square cutout on the underside of "Octopi_With_Pi_Cam_Body".
4. *Optional Step Here - See end*
5. Slide the Pi-Cam-Case assembly into "Pi_Zero_W_Case_Holder" - The orientation depends on your bed height, there's a few mm up and down for adjustment here.
6. Using 2 x M3x10 Bolts, Washers and Nuts, attatch "i3_Frame_Bracket" to the spare mounting locations for Z-Stop switches (On the opposite side to your actual Z-stop). Again, there is a few holes to choose from here for adjusting the height of your camera.
7. Using 1 x M6x5 Bolt and Nut, attach "Arm_Piece_Bolt" to "i3_Frame_Bracket".
8. Using 1 x M6x5 Bolt and Nut, attach "Arm_Piece_Nut" to "Arm_Piece_Bolt".
9. Using 1 x M6x5 Bolt and Nut, attach "Arm_Piece_Bolt" to the Pi-Cam-Case-Holder assembly you completed in Step 5.
10. Sit back and admire your smart new setup!

The mount is adjustable by loosening/tightening the M6 Bolts, the nuts should be retained in the arms. You can also adjust it in the Z direction by using either of the 4 spare Z-Stop locations, and by sliding the Pi Case up and down inside the Holder.

If you need extra length to your arm, simply print off one more of each "Arm_Piece_Bolt" and "Arm_Piece_Nut". You will need an extra 2 x M6x5 Bolts and 2 x M6 Nuts . 

*Optional Step to Monitor Enclosure/Room Temperature*:

1. Solder Pin 1 of the DS18B20+ to a piece of wire. Heatshrink over the connection for added strength.
2. Connect this Wire to the Ground GPIO Pad/Pin on your Pi Zero W.
3. Solder the 4.7k resistor between Pins 2 and 3 on the DS18B20+, Heatshrinking over the connections if desired.
4. Connect a length of wire to Pin 2 of the DS18B20+. Heatshrink over the connection for added strength.
5. Connect this wire to the GPIO4(GPCLK0) Pad/Pin on your Pi Zero W.
6. Connect a length of wire to Pin 3 of the DS18B20+. Heatshrink over the connection for added strength.
7. Connect this wire to the 3V3 Power Pad/Pin on your Pi Zero W.
8. Install the "Room Temperature" Plugin by Frederic Moutin, detailed here: (https://github.com/l00ma/OctoPrint-roomTemp).
9. Run the three wires through the three channels in the Pi Zero W case, and install your sensor in a location of your choosing.

Don't Forget:

• You may need to flip your PiCam Stream. Do this from inside the OctoPrint Web UI.
