Holosight plexi mount

Little bracket that slides into the holosight gap.

It holds a 3mm thick plexi. Size 42x30.5mm (can be 32.5mm if you chamfer the bottom like I did)

This will not obstruct your view and using 3mm plexi also will not distort your view like cheap protectors that you can buy.

Plexi can easily be cut, similar to glass. Scribe a deep cut with a stanley knife and then break the plexi along that line with the help of a ruler.
The chamfer and corners were done with 180 grid sandpaper.

I printed mine in E-sun ABS+ on a bambulab P1S with 0.6mm nozzle. I think 0.4mm would be a bit better. But this worked for me.
