This is a 3D model of the Estes Cherokee-E model rocket (kit #2408) sold exclusively by Hobby Lobby crafts and hobbies stores across the USA.https://www.hobbylobby.com/Crafts-Hobbies/Hobbies-Collecting/Rockets/Cherokee-E-Model-Rocket-Kit/p/80959023
History:
The Estes Cherokee-D was produced from 1970-1983 and designed by Gene Street. This kit used D motors.https://www.rocketreviews.com/cherokee-d---estes-1247-k-47-1971-1983.htmlhttp://www.vintageestesrockets.com/k-kit-registry/kits/k47-astron-cherokee-d.htmhttp://www.ninfinger.org/rockets/nostalgia/70est098.html
From 1987 to1992 AAA Model Aviation Fuels produced and sold a 2.1 (54mm) inch diameter Cherokee-G kit that used G motors.https://www.rocketreviews.com/cherokee-g---aaa-model-aviation-fuels-6-1987-.html
The Cherokee-E by Estes was released in 2019 and uses E motors.https://www.rocketreviews.com/--cherokee-e.html
Differences between the D and the E models:
A) The kit made its first catalog appearance and shipped in 1970 with kit #K-47. The airframe tube was 16.35 inches(415.29mm) long. It had a balsa nose cone with balsa fins were 1/8 inch(3.175mm) thick.
B) Starting in 1971 the kits that were shipped with tubes that were 18 inches(457.2mm) long. Between the beginning and end of its production years the nose cones switched over to plastic and the balsa fin thickness was reduced to 3/32 inch (2.38mm). In 1975 the kit number changed to #1247.
C) The Cherokee-E has been stretched in length even further by 6 inches (152.4mm).
Uses Estes E motors and other motors that are 24mm x 95mm. The kit comes with a motor adapter to allow you to fly with D motors and others that are 24mm x 70mm.
Note: The changes to airframe length was to ensure stability. You can do the same without adding the additional length by adding more weight to the nose cone.

(1) Decal sheet
The STL files for the fins have five different types:
A) Plain, hard edges
B) Rounded edges
C) NACA 0008 airfoil (aka HD0008; 8% thickness, 0% camber)
D) Supersonic airfoil
E) Fin marking guide for use in making your own fins out of balsa or other materials.
There are two fincans available that are for the main rocket and one for an optional booster stage. They have a unrounded, hard-edge version, a rounded version, an airfoiled version, and a supersonic airfoil version. They will fit over BT-55 airframe tubing.
Decals can be printed on decal paper from the pic of the decals posted here.
I have included a preliminary BT-55 fin guide for the Cherokee. Allows fins up to 2.52mm in thickness like the ones in the kit.
7DEC2019 The kit fin alignment guide was added. It is based on the actual dimensions from the kit.
7DEC2019 Added two versions of a BT-55 to 24mm (BT-50 tubing) boat tail.
The first two photos are a standard Cherokee-D with the second being a Goony version of it.
The last two photos are upscales using a J or K motor and the other using an N motor.

Stuph to finish designing:
Design simulated nozzle.
18mm functioning SRBs; Look similar to GEM motors and/or have oblique nose cones.
Let me know if there are any problems with these designs or something I have forgotten to add.
