It will be busy days.
Already or just 3.6mb.

By using the bump map technique from animation and game modeling you can simulate the thread without getting a huge file size. This is how the pieces look in the browser.

On exporting from Sketchup Sucks:
I export them as .dae (collada) but the mesh is a mess.
- usually the models consist of countless, unnamed groups ( I don't like to work with cluttered drawings ) - double vertices ( these you can remove easy with Blender ) - unconsistent normals directions ( these you can't always recalculate automaticly with Blender ) - holes in the mesh
Sometimes I use them as a reference to redraw them in Blender.
I'm working on assets for the webGL interactive models wich is more of a game approuch to modeling so I'm focussing on that. Sinds it is a architectural project we should have the assets also in a Open Source CAD format if we want people to start using them to design houses with BIM. I think.
In FreeCAD you can then export in .ifc wich is a open BIM format that people than can use in other applications if they choose. If a whole house is exported in .ifc it can then be converted into xbim that can be watched in a browser, also offline, wich is low treshhold for everybody.

A brief explanation of webgl.
Programming in native webGL is a bit devious.
By using javascript libraries it makes things a lot simpler.
-three.js [1] /
-babylon.js [2]
-sceneJS [3]
-etc...
Why three.js?
Qgis [4] (Open Source geographic information system) and Blender [5] (Open Source 3D modeling suite) have a three.js exporter plugin [6] [7].
Three.js has loaders for other 3D formats so you can make something in other OS 3D software and load them too.
It's combinable with other javascript libraries like:
-dat.gui.js [8] (GUI for changing variables in JavaScript)
-physijs [9] (Physics plugin for Three.js)
-etc...
It's Open Source and free (MIT license).
