Rear lens cap to suit Canon EF and EF-S lenses.
This is inspired by the design by walter.
The lens cap features a large outer diameter and the nonagon profile is easy to grip when wearing thick gloves.
Printing was performed at 0.1mm allowing for a firm grip with the lens' bayonet.
An infill of 15% was needed to support the top layer within the lens cap. Also, 6 top layers were required to print a smooth surface within the lens cap.
The remainder of the lens cap was printed at 5% infill.
Supports were used to print the bayonet tabs. I have not tried printing the bayonet tabs without support.
