RD_Blade_0 Here is the most recent print assisted by masking tape which is visible around the neck.
RD_Blade_0@sephthestoryteller The original was 5mm. When I tested it, the fit was too tight to stay on.
I uploaded an updated model with a 6mm socket. This one is super loose. Perhaps 5.5mm will do the trick, but I have not tried a 3rd time.
