Started to build a Fliskits Morning Star, and saw that the card stock with both the transition shroud and the 5-fin marking guide was missing. Immediately set out to design a shroud. Some careful measurements and one new technique later (creating a ‘loft’ between two sketches in Fusion 360) and I printed this. The wall thickness in F360 is 0.45mm (set to match the default extruded width on my Prusa MK3). Prusa Slicer has a checkbox for ‘detect thin walls’ which resulted in a wall thickness of about 0.5-0.75mm. Very happy with the result, the centering ring slides about halfway in, and the shroud mates to the larger tube perfectly. Now on to the 5-fin marking guide!
