• a support structure positioned in the camera housing and comprising a proximal end, a distal end, and a tubular end part at the proximal end of the support structure, the tubular end part having an outer face forming a gap with the inner face of the tubular housing part;
• an adhesive in the gap affixing the support structure to the singular housing element;
• and
• a camera module supported by the support structure inside the camera housing, the camera module including an image sensor and a light source positioned at the distal end of the camera lumen adjacent the distal end of the first lumen,
• wherein the outer face of the tubular end part of the support structure and/or the inner face of the tubular housing part of the camera housing are/is provided with ribs, and
• wherein the ribs include two pivot forming ribs arranged diametrically opposite of the tubular end part of the support structure and/or of the tubular housing part of the camera housing and together providing a pivot fit with the corresponding outer face or inner face, and wherein the ribs further include two distance ribs distributed peripherally about the tubular end part of the support structure and/or of the tubular housing part of the camera housing and together providing a distance fit with the corresponding outer face or inner face.
