BMG Extruder Shim

thingiverse

When installing V6 hotend as direct drive setup, I found that the seating isn't secure. For some reason, one side of the BMG body has a narrow (-1.4mm) fit on the front cover (check out the red lines). This allows the hotend to wobble. To fix this issue, printing two 0.7mm shims will make the connection solid on both sides of the hotend neck. Adding a few layers of tape will make the connection even more secure.
