The ultimate tool for warm-hearted men: a sister product to the DC heating station "Warm-hearted Cup Holder".

Due to the prolonged lockdown caused by the pandemic, several projects were progressing slowly, and unfortunately, I was unable to participate in the Spark Program. Although I cannot participate, I will continue to add projects later.

This project was  created out of  
the initial impulse: as the weather got colder, I was worried my wife wouldn't be able to drink water promptly at work, so I quickly modified it to pretend I'm a warm-hearted man ^_-
