Hello everyone!
Thank you very much for your support!
There are 43 cues to go for now. I appreciate those who said they don't expect a cue, you'll get a cue from me anyway

Just putting you to the end of the queue, so the Butterfly Efect system may work properly.
I've chosen the simpliest model and obtainable components so $100 may cover selfcost of the cue + delivery and left something for a donation. Now it's about $15 from a cue. And it's quite good help, frontline stands on small donations from huge amount of people. Today I've got $100 from Jeff and $15 goes to batteries for FPV drones. I'm pretty sure he've came from this thread
Also here is the list of
trusted volunteers
Many of them have websites and socials with a lot of info.
Anyway, besides closing the debt, my goal for now is to add a bit uniqueness to the design. And speed up the processing, so you get a cue shipped straight after donation. I have an ideas, working on it.
All info from the challenge I'm also
collecting here
As for the parameters.
Weight is constant, but you can request any. As well as length, tip and butt diameters.
For the joint pin I've chosen steel metric M6 with metal insert. It's strong and durable. Radial pin is great, but it won't left a place for donation, so the main reason is the cost.
If you want a cue blank instead of a cue, just let me know.
Appreciate your patience and support very much!
Butterfly Effect Challenge is still actual.
