Dexcom G6 Turning Fixture.

thingiverse

This is a customized Lathe Fixture designed for safely machining out the battery compartment of a Dexcom G6 transmitter. To prepare the fixture for use, turn off the machine and detach it from the tab entirely or, if you prefer a more precise approach, carefully drill down until the tab becomes visible (refer to the accompanying photo on the lathe - as the tool makes contact, you will hear a distinct ticking sound). Finish the remaining work by hand.
