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):

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

• Insert the COB LED Strip Light from the top of the base

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

• Add 1 magnet to the top of the filter in the prepared cutout
• Glue the Filter and the tube together
• Add your lable (optional)
• Insert the LED strip into the tube until the magnets naturally attract and align
