Prusa XL Enclosure USB Camera Mount

This is a camera mount for attaching a USB camera (any 38x38mm camera with a 28x28 hole pattern). Originally this was designed to be used with this Arducam IMX291 board which comes with a 100 degree diagonal FOV (90 horizontal, 68 vertical). 

This mounts the camera from the outside of the enclosure since there isn't much space inside the enclosure to capture a full view of the built plate and this helps to avoid overheating of the camera. 

Why is the mount so big? To avoid reflections off the plastic window getting into the camera, the mount roughly covers the entire window space the camera looks through.

How to control the USB camera? You can't directly connect the USB camera to the Prusa board. You will need an external computer (e.g. a Raspberry Pi with OctoPrint) to control the camera.

Installation: 

• 3d Print
  • 1 x xl-camera-mount.stl (requires supports touching build surface. See the picture)
  • 3 x cable-holder.stl (use a brim)
• Attach the camera to the camera mount:
  • Insert the camera from the inside of the mount.
  • Fasten with 4 x M2 6mm screws and 4 x M2 nuts.
• Attaching the camera mount to the front door
  • Use 4 x M4 12mm screws (10mm minimum). This will replace the stock M4 8mm screws.
• Route the camera cable upwards along the edge of the door.
  • The cable-holder.stl parts can be used to hold down the wire
  • Use 2 cable holders attached to the door using M4 10mm screws (replacing existing M4 8mm screws)
  • Use 1 cable holders attached to the top left of the enclosure using an M3 6mm screw and nut into an empty hole.

There is an optional fan-lid.stl that can be printed to mount an extra 30mm 5V fan on top of the camera to prevent overheating. To use it:

• Splice a 30mm fan's power cable into the camera's USB cable.
• Print a fan-lid.stl
• Replace camera mounting screws with 4 x M2 8mm screws
• Add 4 x M3 12mm screws and 4 x M3 nuts for the fan
