Modular Grit Guard

This model is part of the VDetail3D collection – a tag under which I will regularly publish 3D printable accessories related to car detailing. Follow the tag to stay updated with new tool holders and detailing gadgets!

A modular grit guard system that lets you print a full-size bucket insert even on smaller printers like the BambuLab A1 Mini. Designed for easy assembly, solid fit, and real-world detailing use.

📏 Available sizes

• 265 mm – perfect fit for Work Stuff buckets (as shown) – sits tight and won’t move
• 260 mm – ideal for common hardware store buckets (Castorama, Leroy, etc.)

🧩 Key features

• Modular design – print in parts and assemble into a full-size grit guard
• Fits securely in the bucket – no floating or shifting
• Optimized structure for effective dirt separation
• Compatible with standard detailing workflows

🖨️ Print settings

• Material: PETG (recommended)
• ⚠️ Avoid PLA – constant contact with water may degrade it
• No supports required (depending on orientation)
• Standard strength settings are sufficient

🔧 Assembly tips

• After assembling, it’s recommended to glue the parts together for maximum rigidity
• You can use standard CA glue or other plastics-friendly adhesive

📐 Scaling

• The model can be easily scaled in Bambu Studio to fit different bucket sizes
• Just adjust the percentage uniformly to match your bucket diameter

💡 Why modular?

You don’t need a large printer to make large functional parts – just print sections and combine them into a full-size grit guard.

🎨 Customization

You can print individual segments in different colors for a unique look – no AMS required.
