I created one of these stands some time ago in balsa. While it was good and did the job, I figured that with a laser cutter sitting here, I should update it!
Laser cut the flat shape from 3mm acrylic. Use a heat gun to soften the area between the notches & fold up (or down, depending on your working area). Repeat for other end. Place stand on shelf. Place rocket on stand. Step back. Admire.
