Arduino Uno / Mega - Stackable Gridfinity

These custom inserts are designed to hold your Arduino Uno R3 and Mega 2560 R3 boards securely and neatly. The design ensures the electronics sit perfectly flush with the top of the bin. This feature guarantees perfect stackability, allowing you to place other Gridfinity bins directly on top and fully utilize the height of your drawer or box without any interference.

Included Versions:

• Uno Single Slot (2x2 Grid, 4u Height): Holds one Arduino Uno R3.
• Uno Double Slot (2x3 Grid, 4u Height): A space-saving solution that holds two Arduino Uno R3 boards stacked vertically.
  • Note: This version includes built-in “brim ears” at the corners to prevent warping during printing. Please remove them after the print is finished.
• Mega 2560 Slot (2x3 Grid, 4u Height): Holds one Arduino Mega 2560 R3.
  • Note: This version includes built-in “brim ears” at the corners to prevent warping during printing. Please remove them after the print is finished.

Need a specific layout? Currently, these are the available versions, but I am happy to add more based on community feedback. Let me know in the comments if you need a specific size!

 

Material Recommendations: PLA and PETG are the recommended materials for a perfect dimensional fit. Note on ABS/ASA: While it is possible to use ABS, please be aware that due to its higher shrinkage rate, you may need to slightly scale up the model to ensure the stacking alignment is perfect and that the board fits correctly inside the tray.  I haven't personally tested this model with ABS yet, so if you try it, please share your experience in the comments!

 

Logo Removal: I’ve included my logo on the surface using modifiers within the .3mf file. If you prefer a completely clean look without branding, you can easily remove it! Simply open the project in Bambu Studio, select the logo modifiers in the object list, and delete them before printing.

 

Color & Styling: The included .3mf file is pre-configured for easy multi-color printing. The model is already defined with separate parts (bin and lip) within the object list. This allows you to instantly assign a contrasting color to the top rim, exactly as seen in the cover images.
