Inspired by the jacket detail in the Cyberpunk 2077 trailer. Those details on the sleeves. Designed my own but with a bit more mechanical feel. Four slots for 10mm M3 Hex bolts in the top. And the middle hole is sized to fit a 5mm LED. Underneath the central hole is big enough to house the LED and wires without to much hassle. And four holes sized for 15mm M4 bolts to connect them to the jacket. Haven't tried printing it yet.
