Instructions for the Mt. Simon Skeleton and Mini Skeleton 

3D printing: 
1.	The rocket is printed in two separate halves. 
2.	There are files for each individual half. The Mini Skeleton has an additional file that includes both halves. Use the files that are appropriate for your printer’s size. 
3.	It is recommended to print flat with 15% infill.  
4.	Allow pieces to cool completely before removing from the printing plate. 
5.	If you printed using supports, you may need to remove them from inside the launch lug.  Printing without these supports may result in a deformed part.  Use a launch rod or some similar sized object to remove the supports from inside the launch lug.  
6.	The half with the slit in the top slides up under the half with the slit in the bottom, to form a complete rocket Skelton.  You will need to gently spread the fins apart on the top half to clear the recovery stop on the bottom half.  
7.	If painting or decorating the rocket, do not do anything that will interfere with the assembly disassembly mechanism.  This is vital for the rocket’s performance during the recovery phase of flight.  

Pre-flight: 
1.	Rocket is intended to be used with 13 mm mini motors from Estes Industries.  
2.	Flight tests were done using an A10-3T. 
3.	The 1/2A mini motors should work but were not tested.  Do not use the 1/4A Mini motors.  
4.	Insert a motor into the intended space (see pictures) with the nozzle end pointing down.  
5.	Using masking tape to secure the motor to the half that has the slit at the top.  DO NOT tape the motor to the other half or it will interfere with the rocket recovery.  

Flight: 
1.	Launch using a 1/8 launch rod and pad or similar equipment.  
2.	Follow all stand safety steps as outlined by NAR / Estes.  
3.	3..2..1.. LAUNCH!  
4.	During flight, the motor’s ejection charge should partially separate “The Skeleton” and allow the rocket to tumble back to Earth recovery.  

Note: This rocket is intended for multiple flights  However, it will wear out quickly with repeated ejections melting the plastic.  Print replacements if the rocket becomes too damaged to function.
