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.
Swing-Out Towel Arm Hub For 1/2 in PVC
A wall-mounted swivel towel arm that prints in place with its hinge already assembled. It is a 52 x 52 mm wall plate with four 5 mm holes for #8 screws, and a 28 mm hub that turns on a 12 mm pin. The hub has a 21.6 mm socket, 32 mm deep, for 1/2 in schedule 40 PVC (21.3 mm OD) cut to any length, and a #6 screw hole pins the pipe in place. Cone-shaped bearing faces and 0.5 mm gaps let the hub swing about 90° either way, so a drying towel folds flat against the wall.
Idler-Side Swing Arm
This is the pinned side of the front yoke in the 'SG90 Sawtooth-Foot Inchworm Crawler' kit. It is a 5 mm thick, 94 mm long flat arm with an 8 mm radius boss and a 4.3 mm slip-fit bore that rides on the kit's 4 mm steel pin. Its pad edge is 20.1 mm below the pivot and has two 2.6 x 15 mm M3 self-tap pilots at x 64 and 76, where M3x16 screws come up through the front crossbeam.
608 Dead-Wheel Odometry Swing Arm
A spring-loaded swing arm for a passive odometry "dead wheel". It pivots on an 8 mm rod or M8 bolt and carries two stacked 608 bearings (8 x 22 x 7 mm) in a 16.5 mm hub, so your M8-bolt axle and tracking wheel stay square to the floor. Pivot to axle is 70 mm. There is a 4.5 mm hole for a spring or rubber band that keeps the wheel pressed down, and two M3 heat-set bosses 38 mm apart where you can attach your own encoder bracket. It's a cheap stand-in for commercial odometry pods on skid-steer and holonomic rovers.
