Stylish Retractable Ballpoint Pen - with fully functional click mechanism

This is a fully functional retractable ballpoint pen (click pen). It combines elegance, reliability, and practicality, making it a stylish everyday writing tool.

• Retractable click mechanism: smooth, precise, and long-lasting
• Comfortable grip: designed for everyday writing
• Elegant look: minimalistic yet refined
• Durable and reliable: designed for consistent use

The pen is designed to fit the widely available Parker-Style G2 refills (standard ballpoint refills) and standard springs. Thanks to this standard format, you can easily replace the refill and use the pen long-term.

Perfect as a personal pen, office accessory, or a unique gift – this 3D printed click pen delivers both function and elegance.

Included Folders

STL → ready-to-print files

• Use these files directly for 3D printing
• Orientation is already optimized – do not rotate before slicing

STEP → editable CAD files

• For customization, modification, or remixing
• Import into your CAD software to adapt dimensions or design details

3MF → slicer project files

• Contain model orientation and recommended print settings
• Can be opened in most slicers that support the 3MF format

GCODE (Core One) → ready-to-print files

• Prepared specifically for the Prusa Core One 3D printer
• Only use these if you are printing on a Core One – for other printers, slice the STL/3MF files instead.

Print Settings

This is a mechanical model with moving parts, so accurate dimensions and clean surfaces are important. Remove the supports carefully so the mechanism works smoothly. No sanding is required – parts are designed to fit together as printed. Print the parts in the orientation provided in the STL files – do not rotate them, as the geometry and strength rely on this.

Material: PLA (recommended)

Part-specific recommendations

body_1 & cap:

• Layer height: 0.15 mm
• Infill: 15-20 %
• Supports: not required

body_2 & mechanism_2:

• Layer height: 0.10 mm (high detail for precise mechanics)
• Infill: 15-20 %
• Supports: build plate only

mechanism_1:

• Layer height: 0.10 mm (high detail for precise mechanics)
• Infill: 15-20 %
• Do not use supports – too hard to remove

Assembly Instructions

Assemble the parts as shown in the GIF and image above. When screwing the two body parts together, tighten until you feel a distinct click.

Test the click mechanism → the refill should extend and retract smoothly. That’s it – your fully functional 3D printed click pen is ready to use! 🎉
