Customizable MAB Base-10 Blocks Generator

🧮 Customizable MAB Base-10 Blocks Generator!

Transform math lessons into an engaging, hands-on learning experience! This fully parametric generator creates mathematically precise Base-10 (Multibase Arithmetic Block) materials. Perfect for teachers, parents, and homeschooling, it allows you to easily generate tactile learning aids to help kids master addition, subtraction, decimals, and place value.

⚙️ Customizer Features:

• Standard School Presets: Instantly choose between Unit (1s), Rod (10s), Flat (100s), or Block (1000s) with a single click.
• Custom Grid Dimensions: Need a custom 5x5 flat, a 3-unit rod, or a massive grid? Switch to Custom mode and define your own X, Y, and Z unit counts.
• Tactile V-Grooves: Features mathematically aligned 45-degree V-grooves on all faces, making counting, grouping, and separating units incredibly easy and visual.

• Slicer Infill Ready: These STL files generate as 100% solid, water-tight volumes. This allows you to print them completely closed on all 6 sides, letting 

  your slicer manage the internal infill to save up to 85% of filament.

🧠 Behind the Design (For Makers & Moderators)

To ensure maximum printability, dimensional accuracy, and flawless slicer compatibility, this is not a static 3D mesh but a highly optimized CSG-based parametric generator. The underlying OpenSCAD algorithm calculates precise boolean subtractions using 45-degree rotated boxes, avoiding slow and error-prone Minkowski operations.

These rotated cutters automatically generate a clean, support-free V-groove pattern across all six faces of the grid, perfectly delineating the unit blocks. By eliminating any manual CAD-based hollowing, the model exports as a 100% manifold, solid 3D volume. This allows modern slicing engines to dynamically calculate standard infill patterns (such as Gyroid) and layer paths, ensuring the outer walls remain completely sealed, solid, and water-tight while reducing filament usage up to 85%.

🖨️ Print Settings:

To match standard Montessori and primary school curriculums, I highly recommend printing the blocks in these highly recognized colors:

• Units (1s): Yellow
• Rods (10s): Green
• Flats (100s): Blue
• Blocks (1000s): Red
• Material: PLA or PETG (PLA is ideal for crisp, matte educational models).
• Layer Height: 0.16mm or 0.20mm works beautifully.
• Supports: STRICTLY NONE. The V-grooves are designed to bridge flawlessly.
• Infill: Use 10% to 15% infill inside your slicer. This keeps the block completely closed on the outside while making it lightweight and fast to print! For small blocks the infilld oesn't matter much but for the 1000s blocks you need to make it strong enough.
• Walls: Set to 2 or 3 wall loops to guarantee the V-grooves have robust, solid edges.

I love seeing these blocks being used in classrooms and homes. Please upload a photo of your print, and with your permission, I will add it to the main model gallery!

Happy printing!
