StampForge - Customizable SVG to Stamp

StampForge - Customizable SVG Stamps

StampForge is an open-source tool that allows you to create custom stamps from SVG files. This model is designed to be 3D printed and used with the compatible stamp holder (also available for download).

What's included

- STL files for several ready-to-print stamp designs
- The StampForge stamp holder compatible with all generated stamps
- Link to the online StampForge tool where you can create your own custom designs
- Onshape link for customizable stamp holder/stamp base models.

How it works

1. Visit the StampForge web tool: https://itzpere.github.io/stamp-forge/
2. Upload an SVG file or select one from the gallery
3. Change the size, height, and position if needed
4. Download the STL file
5. 3D print your custom stamp
6. Mount it on the included holder and start stamping!

You can also download the base model and add text in slicer or modeling software 
if you prefer

For now i know that all this svgs work

But also i wanted to say after some hours testing and tuning most svg's will not work the reason being is that most svgs are not designed to be extruded to 3D shape making the process of tuning really tidies. There are ways to improve svg processing like importing it to blender that is for what i know perfect for converting them to stl or another way is to manually edit svg so it would work. i probably wont put more efford in making this compatable with every svg it was a fun gurney but it's not worth my time really. i may try from time to time to improve something but i dont guaranty anything 

SVG to 3D: Why It’s Tricky

After testing for hours, I realized most SVGs aren’t designed for 3D extrusion—they often have open paths, complex layers, or messy geometry and tuning them is tedious.

Solutions like Blender (great for SVG-to-STL conversion) or manual SVG edits exist, but I won’t prioritize universal compatibility. This was a fun experiment, but not worth endless effort.

I might tweak things occasionally, but no guarantees. For reliable results, pre-process SVGs in specialized tools.

Short version: It’s possible, but rarely easy.

Printing tips

- Material: flexible fillaments like TPU is recommended for stamp base
- Important: Enable ironing on top surfaces for the best stamping surface 
if not printing in TPU
- Supports: Not needed if printed as oriented correctly
- Note: While TPU is recommended for flexibility, all testing was done with PETG/PLA. Adjust settings accordingly.

Assembly

Mount your printed stamp on the stamp holder by pressing the spring and sliding it into the rails. The holder is designed to keep your stamps in the position and ready to use.

Plans for future updates

• Add more sizes (30mm, 40mm)
• Make more svgs compatible and improve web tool stability - probably won't happened for number of reasons
• Make design more secure (if i learn how ThreeJS works) - done
