Creality Nebula overhead camera mount for Qidi Q2 D3D riser

I wanted to have an overhead camera so I designed this to replace the glass lid holder on the D3D riser with a camera mount.

BOM:

• 3 x M3x4x5 heated inserts (optional)

• 3 x 19x19mm cable tie mounts 3.5mm diameter hole

• 3 x cable ties

• 3 x M3 * 6mm countersunk bolt

• 3 X M3 nuts

• 2 x M3 * 10mm countersunk bolt

• 1 x Creality nebula camera or similar form factor with tripod mount

• 1 x 1/4" camera screw, 5/6" length.

Printing:

You should be able to fit all of these on the plate if you lay the mount diagonally. I used auto-orientation in orca slicer and didn't need any supports. I used gyroid 15% infill but the camera isn't heavy so I don't think it matters too much what you choose.

Instructions:

Print the mount and the two replacement brackets. Take the front two glass holder brackets out of your D3D riser and replace them with the printed replacements.

Insert the 3 heated inserts on the side you wish the cable to run and place the cable tie mounts on top then screw them in with the 6mm bolts. You can just rely on the adhesive if you want but I don't really trust it to stay in place especially above a hot printer. Attach the camera to the mount with the 1/4" screw and use cable ties to manage the cable.

Drop two nuts into the slots on the mount, place it on top of the brackets and screw in from below with the 10mm bolts. This is a bit fiddly as there isn't much room to maneuver. I recommend taking the glass off to give yourself a bit more space and put some cloth on the print bed in case you drop the bolts or nuts so they don't bounce away.

The camera has manual focus so I suggest moving the bed around upper or middle-height, putting something with text on it, then rotating the end of the camera lens until it focuses.
