Vintage Cigarette Lamp

Bring a warm, retro glow to your desk or shelf with this stylized cigarette lamp. The design is clean and modular—three printed parts around a COB LED strip, powered via USB‑C. The yellow “filter” cap acts as a soft diffuser, while the white tube spreads light evenly along the body.

Size: ~230 mm overall height (with base)
Printed parts: 3 (Base, Tube, Filter)

Features

• Simple 3‑part print: Base, Tube (diffuser), Filter (tip).

• USB‑C power: Compact USB‑C adapter PCB hidden in the base. 

• COB strip lighting: 200 mm COB LED strip for uniform glow (no LED hotspots).

• Magnet alignment: Small D5×1 magnets to connect the LED strip to the top

• Screw‑secured: Two M2×4 cylinder‑head screws to mount the USB-C PCB

Note on trademarks: The pictured label area can be left blank or customized with your own graphic/decal. Any brand logos are for decorative/personal use only—do not redistribute trademarked artwork.

Bill of Materials (BOM)

• Filter (tip/diffuser) — Geeetech Yellow PETG

Hardware & Electronics

• 2× M2×4 mm screws (cylinder head) 

• 1× USB‑C adapter PCB (5 V output) Link

• 1× COB LED Strip Light, 200 mm Link

• 5× magnets D5×1 mm (also others can be used) Link

• Heat‑shrink tubing

• Wires to solder the COB LED Strip to the adapter

• 3D-Print Glue

For the label i used the Niimbot D110 with transparent labels, you can also use every other labelling machine.

Print Settings (recommended)

General

• Layer height: 0.20 mm (0.16 mm for extra‑smooth tube)

• Perimeters: 2

• Infill: 10–15% (Gyroid)

• Supports: Only for the base

• Brim: 3–5 mm brim for the tube to avoid edge lift (for the tube and filter)

Material Choices

• Tube (White Matt PLA): PLA diffuses nicely and prints crisp.

• Base (Black PETG): PETG adds heat resistance and weight.

• Filter (Yellow PETG): PETG gives a warm tint and resilience; translucent works best.

Part Orientation

• Base: Print upside down and support the area where the tube will be places

• Tube: Print upright for concentric layer lines and even diffusion.

• Filter: Print upright; enable if you want a smoother cap.

Assembly (add your detailed steps here)

High‑level overview (for now):

1. Mount the USB-C adapter PCB into the base with the M2 screws

1. Insert the COB LED Strip Light from the top of the base

1. Solder the LED Strip to the PCB with two small wires (VCC and GND)

2. Use 4 magnets and heat-shrink them onto the tip of the LED Strip (use clue to secure LED strip to the heat shrink tube)

1. Add 1 magnet to the top of the filter in the prepared cutout

2. Glue the Filter and the tube together

3. Add your lable (optional)

4. Insert the LED strip into the tube until the magnets naturally attract and align
