Cox zip starter resurrected

Recreating unobtanium.
The Cox zip starter is most often missing or broken with the GTP, Stocker, or Indy cars on ebay. This is the first version where the gear pitch was a bit off but still worked. Final version printing now.

I don’t know what gearing they are, but those zip starters look very similar to the SSP Racers from the 70’s and also the Kenner “Smash Up Derby” zip starters.
Looks like Jason has figured it out, but it’s an avenue worth exploring.

Hopefully this time I have the gear pitch dialed in on this version. .25mm does make a difference in gear pitch and eyeballing it with a caliper is not the way to do this. Added a Cox logo and rounded a few edges. Will print when I get home on the big printer and still have to print it diagonally for it to fit decent.

Going to be a while before I can print this. I’m out of PETG and more wont arrive till May 10th. Even the carbon fiber Zytel and natural zytel is all sold out. Everybody with a 3D printer is printing medical PPE.
