Baby cubes

There are other baby cubes here, but I wanted them bigger, stackable like Legos and printable without multi-material unit.

I made those for my 2 years old niece who climbed on a chair and built a 1.5 meter high tower by stacking the blocks.

These are big blocks with a hole under and a stud on the top, so they can be stacked, like very loose Legos. Loose, because since they have one stud, with a high tolerance, they can spin easily. You can reduce the tolerances if you want tighter blocks. The original model included has the number 1, so you have the same font for whatever you want, like the remaining letters (I made only 10 letters out of 26)

I printed them using foodsafe filaments, because babies have a tendency to discover the world through their mouth and lick those blocks, which I admit, might seem yummy with all those bright colors :)

I have no multi-material unit, so I print the block symbol up, and insert a color change in the slicer before the symbol layers.  I printed them using the same two colors for all blocks in a serie: numbers are green, letters are orange, math symbols are blue, emotions are yellow.

With that you can, for example, do basic equations, and ask your kid to pick up the cube representing how he feels.

I hear you say, isn't two year old a little young for basic math ? I'd say it's just a question of perspective, kids can be really more intelligent than you'd think :) I was inspired for this exact thing by the book ‘Computer Engineering for Babies’ which I bought her too. Hum, might be steering her into STEM …

Printed in foodsafe PLA from Filaments.ca

many colors

15% infill

0.2mm layer height (but 0.3 would probably work)

supports for the pin and brim around the cube so corners won't lift (be sure to sand them afterwards for corners to be safe, and you can cover PLA with petroleum jelly for 24 hours to restore colors after sanding)
