Skiing outrigger string guide

This is a [string guide](https://enablingtech.com/collections/superlite-outriggers-parts-accessories/products/string-guide) replacement for a "Superlite Outriggers" from [Enabling Technologies](https://enablingtech.com)

I haven't tested it skiing yet, but it seems to be holding well trying it at home.

I printed in ABS with 100% infill, rotated so that the flat part is flat on the printer bed.

You will need a 3/16" by 1/4" (5mmx6mm) rivet to hold it in place.
