This is a set of 3d printed FRT tuning keys. They are designed to drop into your 1022, then be sanded or otherwise modified until they run smoothly in FRT mode. 

After you get a good tune, remove this device and use it to shape/tune your METAL FRT lever. (Don't ruin your metal lever trying to tune)

These can also be used as disposable FRT levers.

Here are a couple of YouTube videos from AdvancedResetTech, the creators of this design. (The design is free, im just doing the printing)

These are made to order, I don't have a bunch preprinted, I will print them as they are ordered.

I can 3d print lots of other stuff too, just ask.
