Uber Design U180 - part casting

I’ve been following the RC groups thread for the insanely powerful Uber Design U180.

In the thread people were talking about trying to mold motor mounts and mid plates from actual parts. Previously I tried to mold from 3D printed parts and found it frustrating.

Creating 3D printable molds in CAD software is a hassle. The steps are well known. However, for every iterate of the part you need redo the whole mold making process.

I was really happy to find Jason Webb’s OpenSCAD script which does much of the heavy lifting. Check out his project http://www.thingiverse.com/thing:31581 There is also further info on his website. http://jason-webb.info
