Have you ever needed to stand a glowstick up in the ground, if so, this is the thing for you. This stake allows for a glowstick to snuggly fit in the top and then be staked in the ground. The stake has a hole and slot that can be used to attach a small diameter rope to assist with removing the stake from the ground later. I have only tested this with a single brand of glowstick, so some modifications may be required depending on the glowsticks. I also not tested the durability of using a mallet to drive the stake into hard ground so I can't comment on the durability yet. Below is a alink to the Free CAD drawing in case you would like to make any modifications.
