Jet Engine Component; Fan, Metal Blade with Snubber

I used to create models of "Wide cord composite fans" for comparison with propellers.https://www.myminifactory.com/object/3d-print-jet-engine-component-fan-75172This model is the Metal Fan Blade model with Snubber (Midspan shroud) that was mainstream before the birth of "Composite fans".Some large engines with the bypass ratio of 5: 1 have this type, but this is for engines with the bypass ratio of around 1: 1.This type was mostly made of titanium. The following explainable elements were incorporated at this time.① Fan Blade, Metal Blade with Snubber (Midspan Shroud) Full Metal (Titanium) for Low Bypass Turbofan "All (3) Blades" can be removable and assembled by finger simultaneously.② Fan Disk (Partial) having "Dovetail" type slots.
