This spring is tapered so that it can compress down into a thin slice. That will preserve more internal air volume for your successful desktop whomp LEO insertions.
It prints fast and decent without supports. It has been whomp-tested 3 times (no, that's a lie, I only tested it twice). As always, adult supervision is required. Every single part of this whomp rocket and spring is dangerous if used incorrectly.
Note: It's deliberately a tight squeeze around the bottom. This will ensure maximum retention of the spring during transportation of your launching device. No, that's also a lie. I refactored the code and made a small conditional logic error, so the flat 270 degree base gets a “reverse taper”. But it works, and still looks elegant from a top-down view.
If you want a smooth underbelly to your tasteful spring upgrade, I've also included a .gcode file with supports. Does it work? No clue. I'm not wasting 2 hours on that and I hope you don't either.
How much do I care about you, the rocket scientists of the future? Plenty! That's why I rendered it with over 45,000 vertices and took almost 10 minutes of CPU time.
Bonus: it even works upside down. Kind of. It looks sad when you install it that way, but it's a trooper of a spring and will still do your bidding.

Thank you to @tokyo2ooo for a great idea. (https://www.prusaprinters.org/prints/128664-spring-for-desktop-stomp-rocket)
Update: I added a slightly different version (r4) that might work better depending on your filament. Try them both and see what you like. Make some for your friends.
