🔤 Modular Snap Letter Clicker System

Create names, words, keychains, desk displays, and endless custom combinations with this fully modular snap-together letter system!

Unlike fixed-name prints, this system lets you print a small collection of reusable bases and simply swap the letters whenever you want. Build a 3-letter word one minute, then snap together a 10-letter name the next—no reprinting complete assemblies.

Perfect for:

• ✨ Names
• 🎁 Personalized gifts
• 🏫 Teacher and classroom labels
• 🔑 Keychains
• 🎒 Bag tags
• 🏠 Desk displays
• ❤️ Custom messages
• 🎄 Seasonal words and decorations

✅ Secure snap connection

✅ Reusable bases

Why You'll Love It

Traditional personalized prints require a completely different model for every name or word.

With this modular system you simply:

• Print a selection of bases.
• Print only the letters you need.
• Snap them together.
• Rearrange them whenever you like.

Instead of printing hundreds of different base configurations, you only need a handful of reusable bases. Whether you're making a short name like Alex or a long word like Print3DFamilyFidgets, the same parts work together.

This also makes it perfect for selling personalized products at markets and events—you can create custom names and words on the spot without needing to carry every possible configuration.

Recommended Switches

This design is built around MX-style mechanical keyboard switches, giving each button a satisfying tactile feel and an addictive mechanical click.

For the loudest and most satisfying click, I recommend using Blue MX switches, which provide a crisp tactile bump and distinctive click with every press.

Compatible switches can be purchased here:

AliExpress:

You can also experiment with other MX-compatible switches, including:

• 🔵 Blue – Loud, tactile click (recommended)
• 🟤 Brown – Quiet tactile bump
• 🔴 Red – Smooth linear press
• ⚫ Black – Heavier linear press
• 🟢 Green – Extra-heavy tactile click

Each switch type gives the clicker a different feel, allowing you to customise the clicking experience to suit your preference.

Important Print Notes

⚠️ The snap-fit connection has been designed with tight tolerances to provide a secure fit.

For the best results:

• Ensure your printer is properly calibrated.
• Check your flow/extrusion multiplier.
• Verify your dimensional accuracy.
• Avoid over-extrusion.
• Remove any elephant's foot before assembly if necessary.

A well-calibrated printer will produce a satisfying snap fit while still allowing the letters to be swapped with ease.

Assembly

1. Carefully remove the two gold metal pins from the bottom of each MX switch using a pair of pliers or side cutters. These electrical contacts are not required for this project.
2. Press the switch firmly into the printed base until it is fully seated.
3. Snap your chosen letter into the top of the base.
4. Connect additional bases together to build names or words of any length.

No glue required—everything is designed to snap together securely.
