Infill Pattern Test Panel Reference Tile – 5x5 Gridfinity - single print or split to objects and print however you want

Description (IMPORTANT - I linked the 3mf file that is set to pause before adding the top layers because it's the only way I know to expose the infill)  If you are using a 220mm bed you will have to disable the prime tower for space. If you use the STL you will have to do that yourself.

STL vs 3MF note - the 3MF is setup ready to go but the STL is not, split it to objects and you can assign the infill type and % however you want. These are perfect 1x1 tiles so you could print them in smaller batches also if you split to objects in your slicer.  

This Gridfinity-compatible 5x5 reference panel lets you compare 25 different infill patterns in a single print.

Each square uses a different infill type at 15% density, giving you a real-world feel for strength, spacing, and visual style—far beyond what slicer previews show.

Whether you're tuning prints, teaching others, or just want a clean reference in your workspace, this tile makes infill selection fast and obvious.

Why this is useful

• See how each infill actually prints—not just slicer previews

• Compare rigidity, density feel, and structure side-by-side

• Great for dialing in profiles across different printers/materials

• Perfect teaching tool for kids, employees, or maker spaces

• Looks awesome in your Gridfinity setup

Features

• 5x5 Gridfinity-compatible footprint

• 25 unique infill patterns

• All set to 15% density for fair comparison

• Prints in one shot

• Clean labeled layout for quick identification

• Drop-in fit for Gridfinity systems

Print Settings (recommended)

• Layer height: 0.2mm (or your standard)

• Walls: 1-2 I did 1 so I can see through into the sides a bit. 

• Top/Bottom: standard

• Infill: predefined in model (15%) or whatever you want to test, but you have to set it up per object. 

• No supports needed

• PLA recommended (but works with PETG/ASA/etc.)

Pro Tip

Print one in PLA and one in PETG—you’ll immediately see how material changes interact with infill structure.
