The whole point of printing my own bodies is driven by three factors. Getting to a finished body may not be as arduous as I have feared. The good news is I've seen some pretty smooth surfaces in the areas where the printing went well. It'll be time-consuming, given it takes about 16 hours to run that print file. I expect I'll be on a learning curve for a while here. Probably install a new nozzle on the extruder and definitely re-level the bed.

I'll try a different support scheme from the Cura slicer toolset, and maybe tweak the print settings. I'll be attempting to run that print later today. I contacted the author of the print file, and he has sent me a revised file - no extra charge.

That, I suspect, is more a matter of my print setup. The third issue was the top of the cockpit did not print successfully. Even if I had been able to remove the support structure without damage, the body was too thin and light for use in a slotcar. And that relates to the second issue - the body was too thin. One, the support structure was very difficult to remove. I didn't expect my first attempt would be successful, and I wasn't disappointed. I obtained the STL file from the website. That changed a couple of days ago when I tried printing a 1/32nd Porsche 917 slotcar body in PETG. Up until now I have not attempted to print any slotcar bodies.

Almost everything I print now is in either PETG (Polyethylene Terephthalate - Glycol modified) or TPU (ThermoPlastic Urethane). Much of what I have been printing is slotcar related. I have owned a Creality Ender 3 Pro filament printer since January 2020, and been keeping it very busy since then.
