I've discovered various springs from Würth, accessible on their website https://eshop.wuerth.de/is-bin/INTERSHOP.enfinity/WFS/1401-B1-Site/en_US/-/EUR/ViewCatalog-Browse?CatalogCategoryRef=14013510010101%40WuerthGroup-Wuerth-1401&CatalogCategoryID=WEgKD92eIw0AAAFDk3Jcaz5u. I've also found a larger motor on eBay, listed at http://www.ebay.com/itm/181261022748?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT. I've created some adapters and a small gear with a bigger central opening. I've made the hole for the screw in the drum of that gear using thin solder instead of designing it in SCAD.
