NEON-CLAMP – Cyberpunk Desk Bag Hook (20–36 mm desks, support-free, M5 bolt clamp)

NEON-CLAMP is a clamp-on bag hook for desks with a hard-surface, cyberpunk look: faceted octagon-profile hook, vented armour plate, hex vents, circuit-trace engraving on both sides and a crown-cut thumb knob. It clamps to the desk edge – no drilling, no adhesive. The images are path-traced renders. Real print photos are coming soon.

What you need - 1× M5×40 socket head cap screw (ISO 4762 / DIN 912)

- 1× M5 hex nut

- Fits desks ~20–36 mm thick. Tighten by hand, or further with a 4 mm hex key.

Print settings - Supports: none – every part was checked layer by layer; all overhangs are ≤ 45° (the only bridges are 1–3 mm over the engraved traces).

- Material: PETG recommended for the body (PLA+ works for light bags)

- 0.2 mm layers · 4 walls · 30–40 % gyroid infill

- Colours: body black/gunmetal · knob & pad orange (or any accent colour)

Assembly - Drop the M5 nut into the slot on the side of the bottom jaw.

- Press the M5×40 SHCS head into the knob (6 crush ribs hold it; a drop of CA glue is optional).

- Thread the bolt up through the nut from below.

- Set the pad on the bolt tip – it simply rests there and swivels, so it never scratches the desk.

- Slide onto the desk edge and tighten by hand (or with a 4 mm hex key).

Optional: stick a 40×22 mm felt/rubber pad into the recess under the top jaw, and fill the engraved circuit traces with a silver paint marker for extra contrast. Specs - Hook opening 26 mm – fits bag handles, straps, headphones

- Body 100 × 130 × 30 mm, ~75 cm³

- Fully parametric: desk range, hook size, width and clearances can be changed in the script.

Notes Load capacity has not been measured yet – it is intended for everyday bags. Tightening the clamp firmly matters more than infill.
