Custom 3D Letter Lamps – Print Your Own Glow

Take a look at my other models too — maybe there’s another little favorite waiting for you. 🧡✨

3D Letter Lamp with Integrated Stand and Front Cover

Welcome.

With this generator, you can create custom 3D letter lamps. A selected letter or symbol is automatically turned into a printable model. The model consists of a housing and a matching front cover. Optionally, an integrated stand and an LED hole can be enabled.

The generator is prepared for 3D printing and can be adjusted directly in MakerWorld or a compatible customizer. No programming knowledge is required. Simply adjust the values, check the preview, and export the print files.

1. Select a Letter or Symbol

Letter

Here you choose which letter or symbol should be created.

Available characters:

• A–Z
• @
• &
• §

Examples:

• A creates a lamp in the shape of the letter A
• V creates a lamp in the shape of the letter V
• @ creates a lamp in the shape of the @ symbol

The final shape depends strongly on the selected character and font.

2. Font Settings

Font Source

Here you choose which font source should be used.

Available options:

Own Fonts

Uses the fonts built into the generator.

MakerWorld Fonts

Allows the use of additional MakerWorld fonts.

Font

Choose the desired font.

Examples:

• Roboto
• Pacifico
• Montserrat
• Oswald
• Anton
• Poppins
• Raleway
• Playfair Display
• Bebas Neue
• Nunito

The shape of the letter changes significantly depending on the selected font. Wide and stable fonts are usually better suited for 3D printing. Very thin or highly decorative fonts should always be checked carefully in the preview.

Font Size

The font size determines the overall size of the letter.

Recommendations:

With very small font sizes, thin areas may occur. In that case, reduce the wall thickness or choose a more stable font.

3. Housing Settings

The housing is the main body of the letter lamp. It is generated as a hollow letter so there is space inside for lighting.

Housing Depth

The housing depth determines how deep the letter extends backward.

More depth means:

• more internal space
• more stability
• more material usage
• longer print time

Less depth means:

• lighter model
• shorter print time
• less space for lighting

Recommendation:

25–35 mm

Wall Thickness

The wall thickness determines the strength of the outer wall of the letter.

Recommendation:

2–3 mm

A higher wall thickness makes the model stronger, but it may cause issues with thin or narrow font shapes. If parts of the letter become too narrow, reduce the wall thickness or increase the font size.

Back Wall Thickness

The back wall thickness determines the thickness of the rear surface of the housing.

Recommendation:

2 mm

The back wall provides stability and closes the housing at the rear. If enabled, the LED hole is cut through this back wall.

4. Front Cover Settings

The front cover is printed separately and inserted into the housing later. It consists of a visible front surface and an insert lip that fits into the housing.

Cover Thickness

The cover thickness determines the thickness of the visible front surface.

Recommendation:

2 mm

A thicker cover is more stable but lets less light pass through when using translucent material. A thinner cover may appear brighter but is more delicate.

Cover Lip Depth

The cover lip depth determines how far the insert lip extends into the housing.

More depth means:

• better hold
• more stable fit
• possibly harder insertion

Less depth means:

• easier insertion
• less guidance inside the housing

Cover Lip Width

The cover lip width determines how wide the inner insert lip of the cover is.

A wider lip provides better hold. For very thin letter shapes, this value should not be set too high.

Cover Tolerance

The cover tolerance is one of the most important settings.

It determines how much clearance there is between the cover and the housing.

If the cover is too tight:

Increase the cover tolerance

If the cover is too loose:

Decrease the cover tolerance

Reference values:

The correct tolerance depends on your printer, material, slicer profile, and print accuracy. For a first test, 0.15 is a good starting value.

5. LED Hole Settings

The LED hole is optional and should only be enabled if lighting will be installed.

LED Hole

Here you can turn the LED hole on or off.

LED Hole Diameter

This value determines the diameter of the hole.

Examples:

LED Left / Right

This value moves the LED hole horizontally.

• negative value: moves left
• positive value: moves right
• 0: centered

LED Down / Up

This value moves the LED hole vertically.

• negative value: moves down
• positive value: moves up

Important: Always check the position of the LED hole in the preview. Depending on the letter, the hole may otherwise be outside the body or in an unsuitable area.

6. Integrated Stand

The stand can be enabled optionally. When enabled, it is directly connected to the housing and printed together with it.

Stand

When the stand is enabled, the letter can stand more securely on a flat surface.

Size

There are two size modes for the stand.

Auto

The generator automatically calculates the width of the stand based on the font size and additional margin values.

This setting is recommended for most cases.

Manual

You can define the width and height of the stand yourself.

This is useful if the automatic stand does not fit visually or functionally.

Stand Height

The stand height determines how tall the stand will be.

More height means:

• more stability
• stronger connection to the letter
• more visible stand

Less height means:

• more subtle stand
• smaller model
• possibly less stability

Manual Stand Width

This value is only relevant when the size mode is set to Manual.

A wider stand improves stability but requires more space and material.

Manual Stand Height

This value is also only relevant in manual mode.

It determines the height of the manually defined stand.

Extra Left / Right Margin

These values are used in automatic mode.

They add extra width to the left or right side of the stand.

This is useful if a letter appears visually off-center or if its center of gravity is not well balanced.

Stand Left / Right

This value moves the entire stand horizontally.

Use this setting if the letter appears visually tilted or if the center of gravity is not positioned well above the stand.

Body Height Offset

The body height offset moves the letter relative to the stand.

If the letter sits too low:

Increase the value

If the connection to the stand is too small:

Decrease the value

This setting is important to ensure that the letter and stand are properly connected.

Corner Radius

The corner radius determines the rounding of the stand corners.

A higher value creates more rounded corners. A lower value creates sharper, more rectangular edges.

7. Cut Edge

The cut edge trims the lower area of the letter in a straight line.

Normally, this function should remain disabled.

Important Note

The cut edge should not be used together with the stand.

The generator is designed so that either the stand or the cut edge can be active. Both are not intended to be used at the same time, because this could create conflicting geometry.

Use of the cut edge:

• useful if the letter should have a flat lower edge
• not recommended when using the integrated stand

8. Quality

The quality setting determines the resolution of curves and circles in the model.

Recommendation:

96

Lower values:

• faster calculation
• rougher curves

Higher values:

• smoother curves
• longer calculation time

For normal prints, 96 is a good balance between quality and speed.

9. Check the Preview

Always check the preview before exporting.

Pay special attention to:

• Is the letter complete?
• Are thin areas stable enough?
• Is the LED hole in the correct position?
• Does the stand fit the letter visually?
• Is the cover aligned correctly?
• Are there very narrow or problematic areas in the font shape?

For highly decorative fonts or very small sizes, it may be useful to increase the font size or choose a more stable font.

10. Printing

The generator currently creates two relevant print parts.

Plate 1

Plate 1 contains:

• the housing
• the integrated stand, if enabled

This plate must always be printed.

Plate 2

Plate 2 contains:

• the front cover

This plate must also always be printed.

Plate 3

Plate 3 is currently not used.

11. Recommended Starting Values

For a first test print, the following values are recommended:

These values are a good starting point. Depending on your printer, filament, and selected font, small adjustments may be necessary.

12. Troubleshooting

The cover does not fit in

Increase the cover tolerance.

Example:

0.15 → 0.25

The cover is too loose

Decrease the cover tolerance.

Example:

0.25 → 0.15

The letter seems unstable

Possible solutions:

• increase the font size
• increase the wall thickness
• choose a more stable font
• enable the stand

The stand tips over or looks too small

Possible solutions:

• increase the stand height
• increase the stand width
• increase the extra left/right margin
• move the stand left/right

The LED hole is in the wrong position

Adjust the position using:

• LED Left/Right
• LED Down/Up

Then check the preview again.

The font creates faulty or very thin areas

Possible solutions:

• choose a different font
• increase the font size
• reduce the wall thickness
• avoid highly decorative fonts

13. Material Notes

Standard 3D printing materials such as PLA or PETG are suitable for the housing.

For the front cover, translucent or milky filament can be used if light should shine through.

Recommendation:

• Housing: PLA or PETG
• Cover: white, milky, or translucent PLA/PETG

The actual lighting effect depends on the filament, cover thickness, and installed LED lighting.

14. Summary

This generator creates a custom 3D letter lamp from a selected letter or symbol.

The model consists of:

• a hollow housing
• a back wall
• a separate front cover
• optional LED hole
• optional integrated stand
• optional cut edge

Currently, two print parts are used:

Plate 1: Housing, optionally with integrated stand
