Axle end cover/protector for Sturmey-Archer/Shimano Nexus/Sram internal gear hub

I had not seen yet a dedicated protector for the end of the axle of an internal gear hub, a simple but essential bit when packing a bike for shipping: without a protection the end of the axle will perforate the shipping box and be exposed to any sort of damage.

Sure, there are plastic protector caps readily available to local shops, but those are generic so "one size fits all" means "one size fits none". Generic ones won't fit well, so here are specific sized models to fit your internal gear hub, and with a large 80mm outer disc for extra protection.

Each model, “SH” for Shimano Nexus/Alfine, SR for Sram T3/T5, SA for all Sturmey-Archer ones, has a “test” file that you can use to verify that you printer has good dimensional accuracy with a print that will save you time and filament. 
You can always scale +-0.1mm in the slicer. Or if he fit is loose just wrap once (or twice) with electrical tape the end of the axle.

Best results are with TPU, but you can use any material you have on hand.
