Sentinel Model Rocket

This is a replica of the Sentinel model rocket sold by Estes from 1988 through 1994. It is one of my favorite rockets. The photo shows the original Sentinel on the left, and the 3D printed version on the right. The original is 27" tall, the printed one is 21.5"

I scaled it down by .8 so the fin section would fit within the 6" diameter build plate of my Orion Delta printer. The body wall is 1 mm thick, allowing for two extrusions of .5mm.

If your printer's build plate is 8" diameter
