Kinetic Sand Molds
thingiverse
I searched for sand molds online, but they were nowhere to be found, so I created my own drawings instead. I wasn't willing to spend $20 plus $10 shipping for the official wooden molds. The molds I drew may be a bit too large, but that's okay – just adjust them as needed or scale up/down according to your specific needs, aiming for an inner size of about 40mmx40mm per square.
