AngryRatCam - Case Camera for RatRig V-Core 4

Camera module housing to add a OV5648 5MP USB Camera Module to your RatRig V-Core 4 3D printer (or any other printer with 3030 extrusions) 

All credits goes to chri.kai.in for the original design of the Angry CAM USB.

Print instructions:

• enable supports only for the LeftSupport & RightSupport parts
• print flat side down
• standards RatRig print settings : 4x walls, 0.2 layer height, 25% infill
• .4 nozzle size if possible
• if printed with accent color, the RatRig logo on the back cover will benefit from using Arachne
• material : if enclosed, preferably ABS or ASA

BOM:

• 1x CameraBody (printed part)
• 1x Front_Cover_120 (printed part)
• 1x Back_Cover_120 (printed part single or Back_Cover_120_multiparts for accent color)
• 1x LeftSupport (printed part)
• 1x RightSupport (printed part)
• 1x Waveshare OV5648 5MP USB Camera Module (120deg) (Seems to be discontinued, but still available on AliExpress for example)
• 1x USB-A to JST SH PCB connector cable (depending on your printer size, you may need an extension usb cable)
• 2x m6x12mm Hex Socket Head Cap Screws (SHCS)
• 2x m6 T-Nut - Drop In Type for 30 Series

Assembly instructions:

• Add the m6 screws in the supports (round hole)
• Add the T-nuts to the screws
• Choose on which side you want the cable to go and feed the cable through the support ( supports should have the flat side toward the front of the printer (door side))
• Fix the support with the cable slightly off-centered (so that the camera housing is dead center)
• Prepare the camera housing by assembling the camera module housing and the front cover
• Gently press the camera module in the camera housing and on the 3 pins of the front cover
• Slide the camera housing and module on the support fixed on the frame while feeding the cable and connecting it (a pair of tweezers can help, but be carefull ;) )
• Add the other support on the other side of the camera housing and tighten it on the frame
• Add the back cover and adjust the camera angle by rotating the housing
• Connect the USB cable to your Raspberry PI
• Configure Crowsnest & add the camera in Mainsail
