The Elegoo Mini Heater is designed to be mounted on a side of a resin printer. It shouldn't stand on its own, as there's air intake on the bottom. This stand solves that and allows you to use the heater anywhere.

The four leg design allows placement on the uneven bottom of a wrinkly enclosure. You can use the stand to raise the heater either 3 or 5 cm, depending on which side you use.
