Logitech C270 Camera Mount for Prusa MK2/S and MK3, with wide angle lens support.

UPDATE 2: Updated it with a MK3 version of the arm. If it's a bit too snug, sanding the top of the "fork" is the easiest (that goes between the heatbed and Y-Carriage). Naturally the fit will depend on your settings and material. UPDATE: I made a new frontplate to support a 12v 40mm LED ring, with a cover. (C270_WideLens_FrontPlate_LED and C270_WideLens_LED_Cover) I changed all the parts for the C270 camera mount, and made it support a cheap wide angle lens. -It will require an extra M3 screw (plus a washer if the head is small) for attaching the camera to the arm, and an M4 screw to be able to adjust the vertical camera angle. -The frontplate and backplate will require two ~m2.5x12 screws (Notune21 hasn't specified, so this is just a guesstimate). But I used two small m3 wood screws I had laying around, and they seem to have worked just fine. I found the original design hard to keep aimed and the extruder assembly kept bumping into the camera during auto calibration. -The arm has been modified to fit the MK2S buildplate, shortened and made in one piece (removing the need for the printed plastic screw). I also added two slots on the back for zip ties. -The mount that screws directly into the camera has had the groove removed. -The camera parts (back plate, front plate and focus ring) have been modified to support a wide angle lens. I used a cheap magnetic lens made for cellphones.
