LED Light for Desk/Workbench - 3 Step Dimming

A powerful and functional lighting system for desks or workbenches. This model integrates three 3W LED spotlights with a built-in dimming feature.

Main Features

• 3-Step Dimming: Toggle between 100%, 50%, and 20% brightness by simply switching the light off and on (no external dimmer required).
• High Performance: Three 3W LED spotlights provide a total of 9W (approx. 75W halogen equivalent - for 220/230V mains).
• Thermal Management: Features a vented top cover for heat dissipation; the design requires PETG for the internal mounting plate and PLA for all other parts.
• Illuminated Switch: Push button with a blue LED ring for easy location.

Bill of Materials

• LED Spotlights: Kyotech Dimmable LED Recessed Lights (3W, 230V) 
• Switch: Latching Push Button with LED
• Terminal Block: Standard 4-Pole Mammut
• Screws:
  • 2x M3 x 20mm: Secures the terminal block and plate to the body.
  • 2x M2 x 6mm: Lateral plate fixation.
  • 6x M2 x 6mm: For the top cover.

Assembly & Version Notes

The following photos guide you through the assembly process. Please note that the images show the first prototype. During testing, I optimized the design to ensure a perfect fit:

• Improved Plate: The downloadable files include the Updated V2 of the mounting plate, which features trimmed corners for easier insertion into the Main Body.
• Screw Optimization: I removed a redundant central screw hole from the original design to simplify assembly. The files you download are the corrected versions, so you won't need to perform any manual modifications as I did on my prototype.

Step 1: LED Plate Setup

The Main Body requires supports for the internal structures. To achieve a cleaner result and avoid manual touch-ups, a test I would personally do (which I couldn't try as I don't have an AMS) is:

• Use a dedicated Support Interface material.
• Experiment with lower Z and XY distance settings for the supports to ensure better stability for the internal parts.
