ISSF Clip-On Front Blinder and 3mm Iris (Blende)

thingiverse

I modified the blinder to be more compact, making it more comfortable to use with regular glasses. The revised iris now measures 3mm in diameter, allowing for a smooth transition between focus points without appearing as a pinhole or obstructing too much light. Overall, the result is still an affordable option, priced under $2, although the addition of the paperclip does increase the cost.
