Upgrade for Martin's Puzzle Rocket

This is an authorized improvement to Martin's excellent Puzzle Rocket. If you haven't downloaded the original, follow the link above to get it. The files in this model are only the upgraded pieces.

In the pictures, you can see original parts in blue/green and the upgraded parts in magenta.

Changes

• Fins: The new fins have been thickened with a curved channel to fit the original pieces they slide in to.
  
  This design allows them to be printed on their side for significantly increased strength. Most printer/filament combinations should be able to easily bridge the gap.
  
  An interesting side-effect of the new fin design is that it can't be inserted upside down. You're welcome :)
   
• Core rod: The core rod is now separate from the nozzle, and prints lying down.
  
  To do this, it's been dropped below the z-plane by a small amount, flattening it on one side. The threading has also been lengthened and is now on both sides. The flattening makes the piece printable, and by orienting it lying down it's much stronger. As it's entirely internal to the rocket once assembled, there is no cosmetic impact to the finished puzzle.
  
  I've included a brim on the PLA .gcode, which should help.
   
• Nozzle: The top has been adjusted to accept the new threading of the core rod. The bottom has been adjusted to accept the threading on the new exhaust plume, but is still compatible with the original exhaust plume.
    
• Tip: The tip has been adjusted to accept the new threading of the core rod, but is otherwise unchanged.
   
• Exhaust plume: The bottom has been adjusted to thread onto the new nozzle for a more secure fit without glue, but is still compatible with the original nozzle.

Printing instructions

• Print the upgraded parts as-oriented in the .stl file.
   
• Special notes for the core rod
  • Pay attention to the first few layers; the threading needs to build up before it joins with the rest of the piece.
  • If you're having trouble, make sure your sheet is well-cleaned. You can try a smooth PEI sheet instead of a satin or textured one.
  • Consider printing this in PETG for better bed adhesion.
  • As long as the part stays attached to the sheet during printing, it doesn't matter what happens to the underside of the threads (on the flat side). Just clean it up with snips and it should engage the nozzle and tip pieces just fine.

If you don't have the original rocket already, print all of its parts except the fins, nozzle core, and tip. If you're upgrading an existing rocket, you may need replacements for parts 1, 2, and 6 depending on how tightly the original fins are attached.

Acknowledgement

• Thank you McNumber for allowing me to share these upgrades!

Accessories - Wall mount and display stand

• I've also designed and included a wall mount and a static display stand.
• Print these at 0.2mm layer height
• When you print these, gently insert the fin and push until the inner clip “snaps” free. It should then provide a little bit of retention and allow the rocket to be inserted/removed easily.
• I haven't tested the long-term strength of the clips yet, please don't mount it where it can hurt someone if it falls.
