Summary

My original lens cap for my Sony VCL-ECU2 Wide Angle adapter is somewhere in the Niagara river, so I created this replacement. This has the cutouts for the lens hood and fits nice and snug. If you use a .4mm nozzle, the walls should be solid perimeters. Be sure to print in a flexible (TPU/TPE) or similar material to keep from scratching your lens body.

Pro tip, if you print this in clear TPU and use concentric infill, it will double as a white balance cap.
