Hi there, and welcome to the forums!
I had some low profile grips made by Sedsti Skyfaller (he's a forum member, and has a 3D printing shop on the Shapeways site -
https://www.shapeways.com/shops/sedstiskyfallerdesigns).
I can honestly say, they turned out awesome, and feel great, much more comfortable than the stock ones that come with the Graflex!
The grips pop out relatively easily, and here's a few pics so you see the difference between the 2 different types of grip -
I got mine made with small holes near the pommel end so I could insert trimmed down pop rivets in them, to give it a more ESB/TFA look.
Hope this helps!
