Soap Pump Dip-Tube Extender Coupler
This 14 mm × 46 mm coupler extends a soap or lotion pump dip tube that's too short for a taller refill bottle. The pump's original tube pushes into a tapered top socket that grips any tube from 3.6 to 8.4 mm OD. A 4.3 mm bottom socket, 14 mm deep, holds a length of standard 4 mm OD PTFE tube that you cut to reach the bottom of the bottle, so the pump stops drawing air when the bottle is half empty.
Bowden Tendon Guide Block
This guide block is part of the 'SG90 Tendon-Driven Continuum Trunk Arm' kit (print ×3). It takes a 4 mm OD PTFE Bowden tube in a horizontal 4.3 mm bore, 22 mm deep, at z = 8. The bore steps down to a 1.8 mm chamfered fairlead for the 0.8–1.0 mm braided tendon, which keeps the line aimed straight from its capstan into the tube. The block is 30 x 12 x 14 mm. Its 5 mm side ear has a 3.4 mm hole and clamps in the deck's radial slot with an M3x12 screw, a washer and a nut, so you can slide it and swivel it into line.
Trunk Root Plate
This is the root plate of the 'SG90 Tendon-Driven Continuum Trunk Arm' kit: a Ø76 x 8 mm disc that bolts to the tower's top flange with 3x M3 at R34. It clamps the 4 mm OD PTFE backbone in a 4.3 mm bore, locked by an M3x8 set screw threaded into a radial 2.6 mm hole on +X at mid-height. It also has three 4.3 mm x 6 mm Bowden tube sockets at R20 that open downward and step into 1.8 mm tendon holes. The first rolling dome, a Ø12 hub with an R7.5 cap, peaks 9 mm above the plate top.
Venturi Vacuum Gripper Head
A pick-and-place vacuum head that bolts straight to an MGN12H carriage (20 x 20 mm M3 pattern) and clamps a 4 mm OD PTFE/Bowden vacuum line in a split barrel pinched by a single M3 bolt with a captured nut. A Ø10.5 mm counterbore at the bottom seats a suction-cup collar, and a Ø22 mm scallop with two 4.5 mm zip-tie slots cradles the venturi ejector body alongside. Overall 52.5 x 29 x 52 mm.
