Montessori Geometric Cabinet - Tray 6, Quadtrilate

✨ Montessori Geometric Cabinet Tray 6 (Four quadrilaterals) – Homeschool 3D Printable

Are you a homeschooling parent looking to bring authentic Montessori materials into your learning space? This Geometric Cabinet Tray is designed for easy 3D printing, with Montessori-aligned dimensions and design principles, making it ideal for home educators with a 3D printer.

As a homeschooling parent myself, I'm on a mission to recreate faithful, functional Montessori materials optimized for 3D printing. This design reflects careful research into Dr. Maria Montessori’s original philosophy, with practical adaptations for home use.

🔧 Design Features:

• ✅ Optimized for FDM printing – no elephant footing or corner bulging
• ✅ Rounded corners – safe for little hands
• ✅ Sturdy yet efficient – thick enough to last, thin enough to save filament

• ✅ Snug fit – insets fit securely but are easy for children to remove

   

You can print these full size which is true to Montessori's original metric dimensions, but I found them too big for my small homeschool space and ended up printing them all at a reduced size so that they could fit in an A4 paper drawer…. and then decided to just store them in gridfinity boxes. Choose what is best for your environment. 

Traditionally they are presented with the base yellow and the insets blue.
