This was a tough one. It took me three attempts to finally tackle it an I worked more than 3 months on it. Getting a part like this ready without LDPE is almost impossible - I'm glad we have such a tool.
As you may have noticed on PT I'm working on plate gears. I already completed the 14t one (http://www.ldraw.org/cgi-bin/ptdetail.cg.../35446.dat) and I'm working on the 6t. But I miss a photo of the bottom of the 10t one. Anybody got it?
