V wheel modeled after the published schematics on the open builds website.

I only modeled this to have it in solidworks. And now someone else doesnt have to bother with crafting a model to have an openrail wheel in their assembly.

Print it or just buy one from their store.
The concave 'V' shape of this model would seem indicative of probably failure if printed.
Given that it costs $1.50 to buy, or $3.85 for the kit with bearings and bolts, it is hardly cheaper to print it.
