Summary

So this is a remix (but for the life of me I can't find the original, my apologies) of a Keltec Sub2000 Gen 2 rear sight. I made the following changes:

~ Smoothed out the recess hole of the peep
~ Enlarged the peep hole
~ Smoothed out the shaft hole (that just sounds wrong)
~ Added the button that pushes it straight up
~ Added a oval hole to add strength through add'l outer walls

The reason I made this was for the second picture - if you slather some nail polish, then clean away the excess you can add some colour and I wanted to test different colours without having to scrape it clean each time.

Print this with high infill for strength

V2 - Added a couple of strength holes, sloped the peep hole to allow more light to get into the peep ring.

Added Big version (fill cavity with a bright neon paint for sure)
