Famous PlanesFamous Planes is a set of airplanes in kit cards you have to build. Those are perfect gifts ! You can find the whole collection here 😊 !B17Here is the first aircaft a the set : the famous world war two american bomber : the B17, also known as the . The kit is composed of 5 detailed parts. Like all the other planes in the series, it comes as a card from which you have to cut the pieces before putting them together. There are 2 STL files online: "plane.stl" which shows the assembled aircraft and "B17.stl" which is the aicraft still on the card. You only need to print the second one.PrintingPrinting is difficult because the aircraft is precise, it requires a slow speed. The design has been optimized for a 0.4mm or 0.2mm nozzle. I changed the strength of the "hooks", now it is very easy to unhook the plane by hand. The plane and the map are medium in size (see pictures), approximately 14cm.  You can use 0.1 layer height since all important heights are a multiple of 0.1mm. If you go with something different, there might be some tolerances issues.TolerancesYou can use the “tolerances_test file” to try if the tolerances are okay for your printer. They are all 0.2mm tolerances that work perfectly on my tuned ender 3 without “elephant's foot effect” (if you got that problem, you might run into troubles… 😥).If you see that the tolerance test is too loose or too tight you can use the “horizontal expansion setting”.For curaThe setting is called “horizontal expansion” and you can find it in the “shell” section.For PrusaslicerThe setting is called “XY size compensation" and you can find it in the “expert” tab (please tell me if there is a change with an update since I don't use Slicer).If the test is too tight you need to use a negative value and a positive if the test is too loose (for exemple : 0.05mm or -0.1mm).   Happy printing ! 😎
