LED Strip Mount System for Ender 3 S1

LED Strip Mount System for Ender 3 S1

This project is a two-part 3D printable mounting system designed to hold a 30 cm LED strip on an Ender 3 S1 printer without using screws or permanent modifications.

This model is a remix of a design originally created by Colerax.
I remixed it because the original dimensions were not compatible with my printer. However, I really liked the overall concept and structural design, so I redesigned and resized the model to properly fit my machine while keeping the core idea and functionality.

The system consists of:
LED Holder – mounting brackets that attach directly to the printer frame
LED Bridge – a removable strip support where the LED strip is attached

The LED strip (300 mm long, 10 mm wide, 1.5 mm thick) is self-adhesive and mounted directly onto the Bridge component. The design allows for a clean, reversible installation and easy removal.

The goal was to create a mounting solution that:

• Requires no screws

• Does not permanently modify the printer

• Is fully removable

• Is simple to print using FDM

• Provides sufficient support without unnecessary complexity

The system works using a sliding fit mechanism:

• The Bridge slides into the Holders

• The LED strip is attached to the Bridge

Technical Specifications:

LED Strip Compatibility:

• Length: 300 mm

• Width: 10 mm

• Thickness: 1.5 mm

I used this one: https://www.alza.hu/lnled-szalag-30-cm-feher-d6386391.htm

Dimensions:

• Bridge length, thickness, wideness: 300 mm, 1,5 mm, 10 mm

• LED mounting surface width: 10.6 mm (includes tolerance)

• Printer mounting section width: 30.20 mm (built-in clearance)

• Overall structural height: 40 mm

• Built-in tolerances were added to compensate for FDM dimensional variation.

• CAD Design

• Designed in SolidWorks

• Optimized for FDM printing

• No fillets or chamfers

• Sliding fit connection between Bridge and Holder

• No mechanical fasteners required

Printing Recommendations:

• Material: PLA

• Technology: FDM

• Nozzle: 0,4 mm

• Layer height: 0,2 mm

• Infill: 5%

• Holder: printed on its side

• Bridge: printed flat on the bed

Both models are perfectly fit the 220 x 220 print bed. The parts are not designed for heavy mechanical loads. They provide adequate stiffness for LED support but should be handled carefully.

Assembly:

• Print both Holders and the Bridge.

• Slide the Bridge into the Holders.

• Remove the protective layer from the LED strip.

• Attach the LED strip directly onto the Bridge.

• Mount the Holder onto the printer frame.

No glue or screws are required for the mounting structure itself.
The LED strip uses its original adhesive backing.
