IMPORTANT - carefully follow instructions for assembling and printing if small children are going to play with it. I was inspired by a design found at https://www.thingiverse.com/thing:2121444. Unfortunately, the layer lines in the original design can make the barrier supports fragile. To address this issue, I've designed them to be printed separately. ## Printing Print the two braces on their sides to ensure they are solid. Set perimeter layers to an extremely high value instead of infill at 100%. This will make the braces stronger. The base and barrier can be printed as desired. ## Assembly Before painting or gluing, insert the braces into the base using a hard surface to tap them in if needed, then wiggle them back out. This helps verify that the tolerances are accurate before you paint or apply glue. Painting is optional, but make sure not to cover the parts that will be glued together. Glue the pieces together securely, taking care not to use too little glue. The toy needs to withstand rough play from toddlers without breaking easily.
