So. I was getting ready for a vendor golf event, and decided that I wanted to somehow get Rodney Dangerfields putter from Caddyshack - however, optics are so old school when the iPhone has everything needed for the ultimate putter. While out shopping at a sports store, I saw the iPing product (they give their app away, charge $30 for the mount) and I made one - with high hopes that someone wrote the app I so badly wanted.

Do this in any plastic you like - works great in both PLA and ABS. 40% fill should be fine too - I opted for wall thickness on this so that it would just lay down a minimum of shells and call it done. As this part is narrow, when printing in PLA, no brim is really needed. The rear gap should be enough to mount on any putter, and then slide it up the shaft and it should be nice and snug.

Don't try driving with this - however, if you do something crazy - just post pictures.
