Print time depends on the settings, especially the speed, but also the nozzle diameter and height. Another factor to consider is the orientation on the print (vertical print takes much more than horizontal print).
The prusa is a cartesian type of printer, with lead screw for Z axis, that takes longer to move. A printer with delta style is faster due to a “fluidity” in movement.
I have checked your part, but 5+ hours is too much. There is something with your settings that slows down, maybe the layer height. You should communicate also your settings to have a better picture.
On my normal settings, 0.4 mm diameter nozzle, with 0.2mm layer height and speed of 40 mm/s, my slicer shows 3 hours and 58 minutes (including support structure). With my delta printer, from my experience, this time actually translates to around 3 hours and 30 minutes.
I upgraded my nozzle to the E3D with a remote Bowden extruder. Because the carriage is so light, I am printing at 100mm/s without sacrificing any quality. I sliced the STL file in Cura with 50% infill, 0.2mm height, and it came out just under 2 hours.
You should be able to see the printing speed in your slicing program, but it might not work well if you start changing it without knowing the printer’s limitations
It all depends on layer size. What are you printing at? 0.200mm? 0.100mm? A change from one of those to the other (almost) doubles or halves the print time.
Honestly, the better finish you desire for the object, more is the time it takes to print the same. This means the layer size of the objects is a great factor in deciding the print time. Therefore, if you need to print the objects faster, try a nozzle with better size.
