fischertechnik mini motor replacement gears

The fischertechnik [mini motor](https://ft-datenbank.de/details.php?ArticleVariantId=0476d908-2f19-402d-b533-4efcfca704b7) comes with a [pinion and gear adapter](https://ft-datenbank.de/details.php?ArticleVariantId=7c5cd2d2-543e-4848-a165-124a4c4170be). Unfortunately, the smaller [Z11 gears](https://ft-datenbank.de/details.php?ArticleVariantId=24563a6a-c3e4-4e75-8252-b886f720a572) of this adapter are prone to break sooner or later. Proper replacements can be ordered e.g. from the great [fischerfriendsman.de](http://fischerfriendsman.de/index.php?p=6&sp=3#R6809) site, but I was curious if you could also print them. My tests came out fully functional, but I wouldn't want to bet on their durability.

Hint: One of the gears in my images is an original from ft. ;-)
