A profile and channel for your neon
Set the slot width with an allowance for your LED neon. Edit cross-section dimensions on the drawing; quick sizes include 6, 8 and 10 mm, with exact values available as well.
Generate STL frames for LED neon signs
Build a solid base with an LED neon channel along the centerlines of your lettering. Set the frame cross-section, review the 3D model and export STL geometry for print preparation in your slicer.
LED neon: centerlines and 3D print preparation
A 3D base with an LED neon channel
An example of a round profile with a foot and a 6 mm slot. The dimensioned cross-section is shown on the left and the solid lettering frame on the right. The report includes bounds, base volume, separate bodies and the STL watertight volume check.
From centerline paths to an STL model
Prepare paths
Create centerlines in Neon, add them to sources and open 3D print.
Set the cross-section
Choose the base profile and configure slot width, recess depth, bottom thickness and wall thickness.
Review the 3D model
Inspect the frame from different angles and check bounds, base volume, separate body count and STL status.
Export for printing
Save a whole STL or prepare cuts to fit your printer bed. Export cut parts as one STL or separate files in a ZIP archive.
3D frame preview
Orbit, zoom and pan the model. Review the base and channel, overall dimensions and calculated volume before export.
STL export and part splitting
Enter your printer bed dimensions and review the suggested cuts. Export the whole model, cut parts in one STL, or a ZIP with separate STL files and an assembly diagram.
Frequently asked questions
What defines the frame shape?
The base profile follows the centerlines of the selected source. Generate and edit centerlines from silhouettes in the Neon tab.
Can I adjust the channel to my LED neon width?
Yes. Slot width and cross-section dimensions are editable. Print a small sample to check the fit of your neon before printing a full batch.
Can I print a sign larger than the printer bed?
During export, prepare cuts using the printer bed dimensions, review split lines and save the parts as separate STL files.
Do I still need a slicer?
Yes. Orange Cut creates STL geometry. Set part orientation, material, layers, infill and the printer job in your slicer.
