Cờ hiệu cho thép gai 10mm

I needed some indicators for the 10mm rebar temporarly sticking out of the ground

Designed some simple flags with low material consumption and fast printing.

the inside is more 11.3mm than 10mm as the rebar diameter is for the main body, not the true outside with the indendations.

Scale according to the size needed.

I used some left over HIPS leftover, the only flashy color i had anyway.
