Does anyone have any CAD they're willing to share of the G4 Timmy valve?

Because apparently I like torture, I'm looking at designing a similar valve for a cocker.

I just found out that we've got a Makerspace around here - It's a place that has a fully stocked metal shop, wood shop, 3d printer, laser cutter etc, and is open to members 24/7. Student memberships are $30/month, and since it's relatively cheap, I'm thinking that some of these designs might become prototypes. Thinking of hitting up next week's open house to check it out!
