Canon RF 15-30mm F4.5-6.3 IS STM Lens Hood

A lens hood for Canon RF 15-30mm F4.5-6.3 IS STM. Has shape optimized for covering everything just outside the field of view of the lens on its short end. It's length is 34 mm, and it has an integrated deflection spring lock to prevent it from detaching from the lens (however, it is not very effective due to lens' wings shape). Allows for usage of original lens cap.

For best print quality, I advice setting some really big number of perimeters (e.g. 10) so that it is printed using essentially “100% concentric infill”. This achieves two things: outer surfaces come out smooth without “steps” and the hood becomes tough overall.

If the fit seems loose after printing, you can deform the mounting wings a bit to make them wavy so that they provide better grip.
