Parts comb — six slots for desk leads (USB, power, audio, 3 to 8 mm): 1.2 mm fingers, 14 mm long, 3.2 mm entry between the tip bulbs. Push a lead in, the two fingers beside it spread and close round it; pull it out the same way. Two keyholes in the back face hang it on screws (slot up), or it sticks under a desk edge on tape, or a cable tie through the two slots in the spine straps it to a table leg or a monitor arm. tool_rail — the same component sized for screwdrivers, markers and hex keys (7 to 14 mm): 1.6 mm fingers, 22 mm long, 7 mm entry. Keyholes for two wall screws.

Both print flat on the bed, fingers in the bed plane, no support: the bulbs and slot bottoms are vertical walls. PETG is the material for anything flexed daily; PLA holds cables fine but will eventually crack a finger that is spread every day. Root strain at the widest object is ~1.4% (comb) and ~1.7% (rail).

Assumptions (user unavailable): the keyhole screws are pan heads (7 / 8 mm) driven out 3 mm; the slots are sized for the objects listed and no bigger.
