Astrocam staging adapter (and stage)

Astrocam Rocket - Staging Adapter

The default rocket that comes with the Estes Astrocam is single stage.  A surprising oversite on Estes' part as staging is a exciting thing to capture with onboard video, plus you tend to get greater altitudes and again, more exciting videos. 

Regardless,  this simple part replaces the original motor retention cap with one you can fit a BT-50 based first stage to to allow for easy staging.

First stage assembly instructions

Additional Parts needed 

• 68mm of BT-20
• 35mm of BT-50  

Notes

• I use the BT-20 to add a thermal layer between the motor and the printed fin can, and to allow for the motor to be replaced easily. 
• The BT-50 section makes the coupling of the stage smoother and less problematic. 
• The base uses the original Astrocam Rocket motor retention cap to hold the booster motor in place. 
• The fins ‘notch fit’ into the fin can.
• Because they're all separate parts you can print each fin and the center different colors.
• I've included the source STEP file so you can design your own fins if you like. 

Assembly

• put the BT-20 tube into the fin can base
• trial fit the fins into each slot
• put a motor into the BT-20 to give the tube support before the next step
• put CA glue into the slot for a fin then firmly insert the fin until it's flush at the base, wipe off excess, spray on a kicker if you're impatient
• put a small amount of CA on the upper shoulder and add the BT-50 tube
