Interactive Peek-A-Block Replacements

We got a hand me down Fisher Price Incrediblock Activity Center from a friend with several of the peek-a-block accessories. When i finally got around to changing the batteries i learned that some of the blocks are interactive with the receptor on top, telling your child what shape is in the block, complete with sound effects. i also learned that i only had 2 of the 12 possible interactive blocks. and rather than buying a set off ebay, i reversed engineered the ring code that the center uses to differentiate the blocks and made my own personalized blocks.

if you print them all with the code rings down as i intended when designing, the ones with two or more adjacent code rings missing may need support unless you have really good bridging settings.

20% infill of PLA gives them about the same weight as the other blocks which make it nice for use in the fill and spill side of the center.


these are the available Interactive Blocks. I will add the rest as i design them
