We had about 50 Axis M3045-V dome cameras to install at work, and rather than pay the ridiculous price of ~$100/ea for this type of mount made by Axis, I designed this one instead.
This mount was specifically made to fit the M3045-V, but I know it will fit other Axis dome cameras of the same size, particularly the M3005-V, and possibly the newer models like M3065, M3085, etc. Axis doesn't seem to provide any type of dimensioned technical drawing, so I can't confirm. The distance between the 2 mounting holes is 79mm.
I printed these in PETG and they have been happily in use for the past 3 years. Really saved us from having to drill a ton of holes in the tiles for mounting.
Material: PETG, ABS, etc Layer height: 0.2mm worked fine for me Hardware: 6x 3 mm heat-set inserts (5 mm outer diameter)
Other notes: Make sure to print the hooks standing up on their sides for best strength
