SG90 Femur Thigh Servo Link
The thigh (femur) link for the 'SG90 18-DOF Hexapod Walker' kit (print 6). It is a flat 81 x 22 x 4 mm link. The pivot end screws to an SG90/MG90S horn using M2x6 self-tappers: there is a 6 mm through-hole, and a 1.5 mm deep recess (a 9 mm circle plus a 6.5 mm slot) keeps the horn from turning. The other end holds the tibia SG90/MG90S servo in a 23.4 x 12.8 mm pocket 50 mm from the pivot. Its slotted M2 tab slots take tab hole spacings from 26 to 31.6 mm.
