M7(male) to G1/8 (female) Reducer
thingiverse
Hole size 4mm; M7 threads fit perfectly due to the conical shape, which works very well. I will prepare a similar setup for a 1/8 thread as well, but that's for later. For G-code purposes, I sliced layers adaptively like this: 1.4 to 7.6mm with a Layer Height of 0.07. Additionally, I also used 16.23 to 24.45 mm with the same Layer Height of 0.07. The G-code is attached for your convenience; feel free to give it a try. EDIT: I've updated the design to version 2 and modified the 1/8 thread to be conical in shape, which fits perfectly now.
