Swing-Arm Lamp Ballast Base For 1/2 in Post
Freestanding base that turns a clamp-only swing-arm, architect or magnifier lamp into a desk-standing one: a 13 mm socket (45 mm deep) takes the lamp's 1/2 in (12.7 mm) post, and an M5 set screw with a drop-in captured hex nut stops it spinning or lifting out. The 150 mm dish is an open trough you fill with about 430 cm³ of your own scrap washers, nuts or sand for weight, and three 5.5 mm floor holes let you screw it to a bench instead.
SG90 Arm Base Pedestal
The base and yaw-servo housing of the 'SG90 Four-Axis Desktop Robot Arm' kit. It is a hollow 100 x 100 x 40 mm pedestal with a 5 mm top deck. The deck has a 28 x 12.6 mm SG90 window with 2.4 mm M2 ear slots, which puts the yaw shaft at the deck centre. It screws down with four #8 wood screws through Ø4.8 holes in corner columns on an 84 mm square, and a 14 x 8 mm notch lets the servo cable out.
