I have spoken with one of the folks who originated the 3D file. I’m going to take that and mold it, then cast in a heat-hardened acrylic resin. Once a good mold is made I’ll be able to cast many of them pretty quickly. More details when I start working on this.

Excuse my ignorance, but what material are you going to cast these from?
How did this gear workout, I'd like to get 2 of them if yer still printing them
Thanx
Hey Bubba- Still haven't had anyone test one of these gears yet. If you want to volunteer and promise that you'll install it in a few weeks, I'll send you one. I just need a full report back - any undue wear and tear, fitment, gear mesh, etc. I mentioned above a couple people elsewhere volunteered to test these. I mailed them out and both guys vanished. Don't be that guy haha!
I will say that this gear is based on one that's known to work. It's not like it's going to be a total dud and a waste of time. Really, I'm curious about the material more than anything.
If you have the 3d file there are maker folks that would do them in say aluminium. I'd bet the price would come down a bunch if you did a run of 10 or more. Set up time is a big part of production cost. A 12" piece of 6061 3" OD is like $90, guessing $10 per gear material cost. They could cut the teeth full length, then part them off and do the hole. Not o fan of plastic gears myself.
How much will these cost and where you located?
The thought behind a composite/epoxy/urethane/plastic material is that it's the engineered failure point - the fusible link. If you put too strong of a gear in there, other things might get damaged ... things that are more difficult to find than a replacement gear. I know aluminum is fairly soft, but I think the urethane will be a nice middle ground. With my molding/casting process I can rip out a dozen of these in maybe four hours, plus some more time to bake them off in the over so they cure to their full hardness.
@Hamachi I'm in Denver. Haven't gotten a price together yet. If people keep requesting free ones for testing and never responding the price might go up too haha. I don't think they'll be astronomical though. The material isn't cheap but it makes quite a few. There's a little labor. Plus about a buck for a padded mailing envelope.
Have you tried it in your piggy?
Good points. And I have no clue what the gear type it is straight, heical, worm and the drive - broached keyway, square...
I doubt many people put the window up/down more than once a day - good plastic should work fine.
Sad that folks will take your stuff and not report back - it not like you are asking for x-ray failure analyses and computer failure modeling.

Sold my pig a few years ago sadly, I wasn't prepared with the proper pig sty at home yet.. I still daily my 60, which is getting a fully fresh 2F (whenever I have time to assemble the dang thing), and there's an early-ish 40 languishing in my garage that needs ... everything. One day a pig will come back to me though. I'm more ready now.
@charliemeyer007 I've used Xometry and a few of the other places. Most of the "automated quick fab" houses aren't going to cut helical gears in metal. They could 3D print it, but if you go back to the first post ... I just don't think 3D printing is currently robust enough for production parts. I've seen delamination, shattering, warping, cracking, etc. For any time I would consider 3D printing with whatever filament, I can find a urethane product that I can cast as one piece, and to me that has been far more robust. Really, it's pretty streamlined making these at home. I already make several 60 Series parts this way. Website is in my signature if you want to take a gander!
Maybe a nice mod will edit it for you. PM private message is the way to do. I think it is in the envelope icon next to your name at the top right of your screen on a computer

I just reported your post asking to edit out your address
