I ended up also designing a BT-60 to BT-55 boat tail per another's request.

I was really satisfied with the print. I have my printer set on the finest printing setting it has or should I say the finest setting Cura allows me to set my printer at. It takes longer to print things but it's worth it. I still have to sand pieces but not as much. At the moment I'm working on the X-15 found on Thingiverse resize to a BT-60 size and to fly on a D size engine. https://www.thingiverse.com/thing:3048552 I may try to do a build thread here when I get everything printed up and the assembly figured out. I find the printer really handy. |

PLA is not the best choice for 3D printed model rocket parts. I have had to reprint almost all of the parts I made from PLA in either ABS or some other higher temperature filament like Nylon or PETG. I have two Creality Ender 2 printers and now an Ender 3. I built enclosures out of Styrofoam for the Ender 2 printers that allow me to print with ABS filament. I also use the CURA slicer software that comes with the Creality printers. I have owned 3D printers for about 2 years and have printed thousands of model rocket parts. After about 3 to 6 months I noticed all of the PLA nosecones I made were very loose fitting, much more so than when they were originally 3D printed. All the tail cones I made and flew in model rockets curled and wrinkled at the bottom where they were either exposed to hot exhaust and/or the motor mount tube. All the fins on the fin cans I 3D printed with PLA warped and looked liked Lasagna noodles! The full rockets I printed in PLA now have a distinct bend in them. There is a good reason Additive Aerospace only uses PET plastic for the parts they sell: https://www.additiveaerospace.com/
