Puzzle for children under 2 years
My granddaughter is almost 9 months old and is learning to fit pieces into others.
So I thought about increasing t...he difficulty of the classic baby puzzle and I designed the pieces with a helical guideline.
I know it is for older ages but it is not bad that I try it from time to time and see how it progresses.
When a piece is slightly inserted into its place, a curious effect is produced: when the piece is released, it begins to rotate as it enters by itself due to the effect of gravity.
The main piece that acts as a perforated box is 30 mm high while the pieces to fit are 50 mm. This allows that when lifting the box with inserted pieces, these take a little longer to come out due to the aforementioned rotation.
On 05/12/2017 I have added a 15 cm pentagonal piece since I have seen that my granddaughter likes to see the piece rotate when inserting it into place. Thus, being longer, it lasts longer.

materials
------------
PLA
0.23mm layer
wall thickness 1 mm
filling 0%
without supports
horizontal expansion = -0.1 mm
It is preferable to u...se a different color for each piece.
No post-processing is necessary.
If you prefer that all the pieces are of the same height, the printing must be stopped when it exceeds 30 mm
