Scale Square

A small tray used for weighing larger / multiple objects on a tray.

I needed a way to count multiple RFID tags and figured that using a scale to weigh a single tag, then using the weight of multiple tags would be much more efficient than counting hundreds of tags one by one, however, stacking the tags on a scale didn't work since my fingers would change the weights when building a tower, or the tower would fall over and cause me to reset.

Then, my "scale square" was born. Just throw them in and BAM! You got your weight!
