Logitech C270 mount for Hephestos 2

thingiverse

This device enables you to attach a Logitech C270 USB camera to your Hephestos 2's Y-carriage, allowing it to move in sync with the bed during printing and provide an unobstructed view of the print process. The camera is designed to be mounted into two existing M4 holes on the front of the Hephestos 2's Y-carriage. The lens is positioned along the center line of the bed, while the camera's front is just outside the movement area of the print head, ensuring no interference with printing. Note: I've used this setup for four months without noticing any print artifacts caused by the added weight, but results may vary. Additionally, high prints might exceed the camera's visible angle - I'm looking into mounting a wide-angle attachment or adjusting the camera's position to compensate for this issue. If you're concerned about these potential drawbacks, this solution might not be ideal. To build this device, you'll need to print: 1 x cameramount_bracket_left.stl 1 x cameramount_bracket_right.stl (with support from platform) 1 x cameramount_arm_c270.stl (with support for the two hinge components) Alternatively, you can print a single part: 1 x cameramount_plate.stl (with support as above, designed to fit on your Hephestos 2's bed) You'll also need: 2 x M4x10mm screws (e.g. DIN 912) 2 x M3x16mm screws (e.g. DIN 912) 1 x M3x30mm screw (e.g. DIN 912) 3 x M3 hex nut (e.g. DIN 934) If you need to make adjustments or support another camera model, the Fusion360 files are available. Print Settings: Printer: Hephestos 2 Rafts: No Supports: Yes Resolution: 0.2mm layer height Infill: 15% Notes: The right bracket and the camera arm require supports during printing. I printed all parts in orange PLA with two perimeters. Post-Printing Instructions: Exploded View: Refer to the exploded view for assembly instructions. A textual description follows: Unmount the print bed assembly from the Y carriage. In the front corners of the carriage/bed holder, you'll find two unused M4 tapped screw holes. Use the two M4x10mm screws to mount the left and right brackets into these holes. The bracket halves should wrap around the front of the carriage and come together in the center. Using the two M3x16mm screws and M3 nuts, secure the camera arm to the center joint. Detach the stock clip from the Logitech C270 web cam by removing the hinge - this is a reversible process. Mount the camera to the arm using the M3x30mm screw and another M3 nut. Ensure the cord can't catch on the bed in any way. I used spiral wire tubing to bend it safely and secured the other end onto the front frame with velcro.
