I used PLA with 0.2 layer, but it can be worth to try print the axis with finest layer. The axis is cut into 2 parts that should be glued together.
No supports are required for printing Thing parts.
The yellow support consists of 2 triangle symmetric parts:
- SpoolHandle-a.stl / SpoolHandle-b.stl (6 mm printer frame)
- SpoolHandle-a-frame7.5.stl / SpoolHandle-b-frame7.5.stl (7.5 mm printer frame)
For printing I used 40% honeycomb fill - it's rigid as hell.
