Canon RF 100-400mm F5.6-8 IS USM Lens Hood

A lens hood for Canon RF 100-400mm F5.6-8 IS USM. It's length is 60 mm, and it has an integrated deflection spring lock to prevent it from detaching from the lens. 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.
