I just finished playing VR, and boy are my arms tired!
Nintendo's Labo VR is, to be perfectly honest, pretty impressive. Despite the relatively low resolution of the Switch screen, it presents a remarkably solid virtual reality experience. It does, however, have one weakness. Labo VR doesn't have a strap. With a VR update for The Legend of Zelda: Breath of the Wild just a couple weeks away, I needed a solution, and fast!
The elastic bands that I used to make the strap can be found here.
