Under-Bottom-Bracket V-Seat Cable Guide
A bolt-on replacement for the snapped plastic cable guide under a bicycle bottom bracket. It's 44 x 24 mm, with a 20° V-seat that centres on the BB shell for most shell diameters and stops the guide from rotating on its single bolt. It has two 2.2 mm wide x 2.5 mm deep grooves for bare derailleur inner cables and a 5.5 mm M5 clearance hole, counterbored 10 mm wide x 2 mm deep for the screw head.
31.8 mm Snap-On Bike Cable Guide
A cable-housing guide that snaps onto a 31.8 mm bike down tube (the C-clip wraps 220°) and is locked in place with a zip tie that runs in a 5 mm groove. It has three 22 mm-long channels: two 4.6 mm bores for 4 mm shift housing and one 5.6 mm bore for 5 mm brake housing. It replaces worn or missing brazed-on and moulded guides without frame-specific bosses, and you can set TUBE to 28.6 or 34.9 in the script for those tube sizes.
Wrist Tendon Guide Comb
Upright 80 x 20 x 24 mm comb for the 'SG90 Tendon-Driven Robot Hand' kit. It bolts to the Five-Servo Forearm Deck with 2x M3x10 bolts and nuts through Ø3.4 mm holes at (112, ±20), and runs 10 tendons of 0.5–0.8 mm nylon line through Ø2.0 mm guide holes. The guide holes sit at the flexor height (17 mm) and extensor height (5 mm) for each finger lane. Each hole has a 45° countersink widening to Ø5 on the spool side, so lines that come in at an angle don't fray on a sharp printed edge.
