I designed this stacker toy for my son, who loves stacking shapes up.  This model will fit on the A1 mini or larger beds and requires no AMS as each piece is on its own plate.  

In the original size model each piece is baby friendly, large enough that they are not choking hazards (smallest piece is 3 inches or 79mm).  The smaller scaled model is for older toddlers (smallest piece is 2 inches or 50mm).   

The profiles are set to 0.20 layer height but you can speed it up to 0.24 for a faster print.  You can also scale the original model up or down if you'd prefer.
