In the coming weeks I will be making a taller modular version that could possibly be used as a flying model rocket. Stay tuned.
Prints with custom cylindrical supports included in the stl. About 230mm tall at 100% Z-scale.
Main fuselage is hollow 1.0mm wall.
The rest of the model is solid. If you print with single perimeter of .5 - .6mm, and zero infill the model will be somewhat fragile and you may get some gaps. Two perimeters, or a single perimeter of 1.0+ mm is better. I recommend using a brim of 3.0 mm or more to make sure the separate, small fin perimeters remain secure until they join together at higher layers.
Use whatever retraction length and speed gives good quality on your printer. I use 2mm at 30mm/s on the Artemis.
Set "minimum travel after retraction" to 5 mm or more to prevent retractions while printing the perforated layers on the support cylinders. Otherwise the retractions there will starve the print head of material and cause under-extrusion on one of the fins until the flow normalizes.
If you scale the model to 200%, set it to 10 mm.
