What's a sandbox without mini toys and molds to go along with it? I created these sand Tools for my Mini classic turtle sandbox design featured here: https://makerworld.com/en/models/437362#profileId-342558
I made a bucket with a handle, a shovel, a rake, and not one but 2 different castle type molds. Kinetic sand works wonderfully in the molds.
these are small parts so make sure your bed is clean so that you have good bed adhesion.
The bucket handle might need rotated to be pressed into place. after the initial placement it should rotate freely.
