Made a shape tray toy for my 4 month old to play with so he can practice fine motor skills adn eventually learn shapes and colours.
The tray is large and bulky to make it harder to toss on the floor. It's also nicely rounded to make it nicer to touch.
The shapes are nicely rounded and beveled we well to remove any sharp edges and corners.
Print the shapes in different colors for some visual interest.
Fusion360 file included in case you'd like to make some adjustments.
The tray is rather large at 190x230mm. Will need a large bed to fit it. I printed at 0.4 layer height to try and speed up the print, but even so it took 9 hours. I would recommend printing it at 0.2 just to make the rounded top edge nice and smooth. 0.4 leaves it a little chunky. I used 15% cubic infill and 2 walls with a 0.6 nozzle. Make adjustments as needed to make it durable so it can withstand some abuse.
The shapes are printed with 0.2 layers, 3 walls, 5 top and bottom layers and 20% infill to give them some durability and a hefty feel. Each shape took about an hour.

I'm a perfectionist who likes making custom things, and building a reprap printer scratches those itches perfectly. There's nothing more satisfying than designing a part to fix a specific problem and pulling off the perfect print to do it.
