The Wormbox gears are from a garage door opener. I think I might have had a small part in initiating the concept for this gearbox? Anyways, the gears in my garage door openers (in service for almost 20 years) have been really good as far as strength, the only problems they normally encounter is wear due to lack of lubrication, and wear due to the shaft bushings wearing out when they also are not properly lubricated.
