Flashforge Dreamer or Creator Dial Gauge/Indicator Holder 8mm Hole

Shrank the hole to 8mm. Customised with 3D Slash as a test.
Edit: Hole is too small - about 7.2 to 7.3mm. Going to try a different program.

Ended up using TinkerCAD to make an 8mm hole. After printing, the hole was too small, so made one with 8.75mm hole, which fits my gauge.
