Vudoo Empty Chamber Indicator

Since magazine blocks aren't acceptable for PRS matches anymore I designed this ECI to meet the requirement for something to protrude into the chamber. Other flags I tried either fell out or were finicky to get in. This one stays in place and is easy to insert.

It's designed for a Vudoo V22. It will not fit Begara's B14r. If you try it with a different action drop a comment on whether or not it worked and I'll update this description.

After printing, glue a piece of filament in the hole in the top and glue a magnet in from the bottom. I use [these 10mm ring magnets.](https://www.amazon.com/gp/product/B0BJF129GY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) I like to stick the filament in with some superglue, drop the magnet in, and fill the whole thing with epoxy.

There's not much surface area in contact with the bed, so I recommend using a brim to help with adhesion. Supports are required. Material doesn't matter, but something bright is standard for ECIs.
