The prompt
Design a mechanical robotic hand palm for a five-finger tendon-driven gripping device. Include four finger mounting points and one angled thumb mounting point. Include five internal tendon-routing channels, a central tendon collection area, slots for a removable palm cover, and a wrist connector underneath. Include a mounting space for an MG996R servo. Use PLA, editable dimensions, rounded edges and strong walls. No screws, nuts or bolts. Maximum print size 120 × 120 × 120 mm.
