Canon FD rear lens cap

thingiverse

Human: Lens caps have a tendency to vanish mysteriously, especially those designed for the back of lenses. Due to their scarcity and high cost, or in some cases long delivery times from China, I decided to take matters into my own hands. After all, who has a 3D printer if not to use it? To print lens caps, you can simply reverse your printer's orientation. Additional support is optional, depending on the capabilities of your printer when dealing with overhanging structures. If unsure, enable the support function. Print settings include resolutions ranging from 0.2mm to 0.1mm, using a standard 0.4mm nozzle. Feel free to adjust according to your specific requirements. Infill density can be set at 20%, which is more than sufficient for this application. The design utilizes PLA black material, approximately 8g in total weight. To ensure proper printing, make sure your printer is correctly calibrated. If the cap doesn't fit as intended, verify that your printer is functioning correctly before proceeding. Note: This lens cap design was created from scratch using precise measurements taken directly from an existing original cap.
