Chức danh Người giữ thẻ ID công ty hoặc người giữ huy hiệu

A holder for a company badge or ID card. For me, it works quite well.

Print instructions: Use a brim of 5 mm and print upright standing on the short side, so that the edges holding the card are not printed as overhangs. Otherwise I used a 0.4mm nozzle and 0.2mm layer hight, but that is not so important, I guess.
