Fanttik F2 Master End Cap

So I got tired of the F2 Master Tool falling out of the case, even though it is magnetic; the magnets are weak. If the case is upside down and you grab it, sometimes the tool will drop out. This is designed for TPU. If you print it in PLA or PETG, you will need to increase the X and Y dimensions by .2mm. Fanttik supplies a rubber cap for the NEX S1 Pro, but not the F2 Master.
